I've been given a table with a few fields that hold comma-separated values (either blank or Y/N) like so (and the field name where this data is stored is People_Notified):
Y,,N,
,Y,,N
,,N,Y
Each 'slot' relates to a particular field value and I need to now include that particular field name in the string as well (in this case Parent, Admin, Police and Medical) but inserting a "N" if the current value is blank but leaving the existing Y's and N's in place. So for the above example, where there are four known slots, I would want a tsql statement to end up with:
Parent=Y,Admin=N,Police=N,Medical=N
Parent=N,Admin=Y,Police=N,Medical=N
Parent=N,Admin=N,Police=N,Medical=Y
I tried to use a combination of CHARINDEX and CASE but haven't figured a way to make this work.

Although a bit messy, in theory can be done in one statement:
select
'Parent=' +stuff((stuff((stuff(
substring((replace(
(','+(replace((replace(#People_Notified,',,,',',N,N,')),',,',',N,'))+','),',,',',N,')),2,7),7,0,
'Medical=')),5,0,'Police=')),3,0,'Admin=')
broken down is easier to follow:
declare #People_Notified varchar(100)=',,Y,Y' -- test variable
-- Insert Ns
set #People_Notified= (select replace(#People_Notified,',,,',',N,N,')) -- case two consecutive missing
set #People_Notified= (select replace(#People_Notified,',,',',N,')) -- case one missing
set #People_Notified= (select replace((','+#People_Notified+','),',,',',N,')) -- case start or end missing
set #People_Notified= substring(#People_Notified,2,7) -- remove extra commas added previously
-- Stuff the labels
select 'Parent=' +stuff((stuff((stuff(#People_Notified,7,0,'Medical=')),5,0,'Police=')),3,0,'Admin=')
If you're able to use XQuery in SQL Server, I don't think you need to get too complex. You could do something like this:
SELECT CONVERT(XML, REPLACE('<pn>' + REPLACE(People_Notified, ',', '</pn><pn>') + '</pn>', '<pn></pn>', '<pn>N</pn>')).query('
concat("Parent=", data(/pn[1])[1], ",Admin=", data(/pn[2])[1], ",Police=", data(/pn[3])[1], ",Medical=", data(/pn[4])[1])
')
FROM ...
Explanation: Construct an XML-like string out of the original delimited string by replacing commas with closing and opening tags. Add an opening tag to the start and a closing tag to the end. Replace each empty element with one containing "N". Convert the XML-like string into actual XML data so that you can use XQuery. Then just concatenate what you need using concat() and the right indexes for the elements' data.
Here's one way to do it:
;WITH cteXML (Id, Notified)
AS
(
SELECT Id,
CONVERT(XML,'<Notified><YN>'
+ REPLACE([notified],',', '</YN><YN>')
+ '</YN></Notified>') AS Notified
FROM People_Notified
)
select id,
'Parent=' + case Notified.value('/Notified[1]/YN[1]','varchar(1)') when '' then 'N' else Notified.value('/Notified[1]/YN[1]','varchar(1)') end + ',' +
'Admin=' + case Notified.value('/Notified[1]/YN[2]','varchar(1)') when '' then 'N' else Notified.value('/Notified[1]/YN[2]','varchar(1)') end + ',' +
'Police=' + case Notified.value('/Notified[1]/YN[3]','varchar(1)') when '' then 'N' else Notified.value('/Notified[1]/YN[3]','varchar(1)') end + ',' +
'Medical=' + case Notified.value('/Notified[1]/YN[4]','varchar(1)') when '' then 'N' else Notified.value('/Notified[1]/YN[4]','varchar(1)') end Notified
from cteXML

I'm wonder how I can pass a Postgres function to a field in an insert statement in Psycopg2. Looked everywhere in the doc but can't find the answer.
The code:
From the DBconn class:
def insert(self, table, data):
fields = data.keys()
sql = "INSERT INTO " + table + "("
sql += ",".join(fields) + ") VALUES (" + ",".join(["%s"]*len(fields)) + ");"
self.cur.execute(sql, data.values())
And when calling this function:
db.insert("tblpeople", {"person_name":"john", "org_id":"currval('tblorganisations_org_id_seq')"})
So the question is how can I tell Psycopg2 that the org_id value is a Postgres function?
Tnx!
Your code is producing the statement:
INSERT INTO tblpeople (org_id,person_name) VALUES (%s,%s);
and you are passing 2 arguments. That won't work. You want to produce this code:
INSERT INTO tblpeople (org_id,person_name)
VALUES (currval('tblorganisations_org_id_seq'),%s);
and then pass a single argument. I don't see any way of doing that with your current data structure. If you add another piece of data to your dictionary, like:
{
"text":{"person_name":"john"},
"function":{"org_id":"currval('tblorganisations_org_id_seq')"}
}
and change your constructor to produce the proper query based upon the 'function' key, or, you could 'hard code' your query builder to recognize the 'currval(' being at the beginning of the value. Anyway, the basic problem is you are passing the data as a string argument which won't be handled correctly.

Is there a automation tool which can automate the software build on Team Developer (v6.0).
I have tried with multiple automation tools to spy the table object in the application, it identifies it as Gupta ChildTable. But I am not able to retrieve the values from the row.
For example:
1. I have 10 rows in the table(grid) with 12 columns. I need to find the value "AAAAA" contained in first column and select that particular row via Automation.
2. I have 10 rows in the table(grid) with 12 columns. I need to find the value "AAAAA" contained in first column and click on particular cell in that row to input the data via Automation.
Thanks in advance.
Use VisTblFindString . This function ( and many others ) are included into your TD code if include 'VT.apl' in your include libraries .
VisTblFindString will return the Row - so then you simply set context to that row using SalTblSetContext( hWndForm, nRow ) , and then you can refer to the contents of each cell by name to return the value.
Syntax
nRow = VisTblFindString(hWndTable, nStartRow, hWndColumn, sString)
Handle: hWndTable
Number: nStartRow
Number: hWndColumn
String: sString
Description
Locates a string value within a column.
The string must match exactly, but case is ignored. Searching ends when the last row in the table is checked. A SAM_FetchRow message is sent for all rows that have not yet been fetched into the cache.
You can use the pattern matching characters understood by the function SalStrScan. The percent character (%) matches any set of characters. The underscore character ( _ ) matches any single character.
Parameters
hWndTable Table window handle.
nStartRow Row number at which to start the search.
hWndColumn Handle of column to search. Use hWndNULL to search all string columns.
sString String for which to search.
Return Value
Number: The row number if sString is found, or -1 if not found.
Example:
Set nRow = VisTblFindString (twOrders, 0, colDesc, 'AAAAAA')
Call SalTblSetContext( twOrders , nRow )
( Now you can get the value of any cell in nRow by referring to the Column Name )
e.g. Set sCellValue = twOrders.colDesc or Set sCellValue = twOrders.colId etc.
Rows ( or anything what-so-ever in a TableWindow - even the cell borders , backgrounds , lines, row headers etc ) can be treat as an 'Item' or 'Object' by TeamDeveloper . Recommend you use MTbl - it is an invaluable set of add-on functions that make dealing with Tables a breeze. I know of no sites using TableWindows that don't use MTbl. In terms of rows , you can define any row as an Item or Object and manipulate it accordingly. See M!Tbl ( a TableWindows extention ) and specifically fcMTblItem.DefineAsRow( hWndTbl, nRow ).
BTW , you can also use MTbl to completely change the look and feel of your TableWindows , to give them a real modern look.
Very rough napkin code, don't have TD on this computer. Not that you can copy&paste this easily anyway due to the code structure, only line by line.
tbl1 is the name of the table, col1 is the name of the column, substitute to fit your program.
Set nRow = TBL_MinRow
While SalTblFindNextRow( tbl1, nRow, 0, 0 )
Call SalTblSetContext( tbl1, nRow )
If tbl1.col1 = "AAAAA"
Call SalTblSetFocusCell( tbl1, nRow, tbl1.col1, 0, -1 )
Break
This should run through each row, check whether col1 has the chosen value, and then activates edit mode for that cell - provided the column is editable.
I have a Firebird 2.5 database .As an example I have stored procedure with a name QRESULT which expected return is:
Parameter - DATATYPE
a - date
b - numeric(18,0)
c - integer
d - varchar(50)
and so on....
I use PHP - PDO to query the firebird database using the procedure QRESULT like this:
SELECT a,b,d from QRESULT() where a = "some value"
I need to run some query before QRESULT procedure and i need it to return the datatype of all the columns that QRESULT would return if it was ran. So i can help user to type proper value for my "where" clause.I know i can set that manually in the user interface, but in the real project there are lots of procedures and if there is a way i can make my filter interface generate dynamically i would be happy about that.If this is not possible for a stored procedure i can make it with select statements.I just need some lead.
The information you want is in the RDB$PROCEDURE_PARAMETERS table, basically what you need is query
SELECT r.RDB$PARAMETER_NAME ParName, F.RDB$FIELD_TYPE ParType
FROM RDB$PROCEDURE_PARAMETERS r
JOIN RDB$FIELDS F ON(F.RDB$FIELD_NAME = R.RDB$FIELD_SOURCE)
WHERE r.RDB$PROCEDURE_NAME = 'QRESULT'
AND r.RDB$PARAMETER_TYPE = 1
ORDER BY r.RDB$PARAMETER_TYPE, r.RDB$PARAMETER_NUMBER
Note that the SP name should be in upper case as this is how it is stored into system tables (unless you use quoted identifiers). If you want to get both input and output parameters the delete the r.RDB$PARAMETER_TYPE = 1 predicate from the WHERE (type 0 is input parameters and 1 is output).
The type returned by this query is integer id for the type, quick googling found this:
14,"TEXT "
7,"SHORT "
8,"LONG "
9,"QUAD "
10,"FLOAT "
27,"DOUBLE "
35,"TIMESTAMP "
37,"VARYING "
261,"BLOB "
40,"CSTRING "
45,"BLOB_ID "
12,"DATE "
13,"TIME "
16,"INT64 "
but if you want to have more precise type then see this SO post.
I have a report that brings total sales and total probability sale.
The request was that this be shown in one table as "R"{totalamount}" (R"{totprobamount")".
So i added this together in a variable with the variable expression being
"R" + $F{Totalt} +" (R" + $F{Totalp} +")"
but by doing this the Thousands separator does not show anymore?
If you can add a field for each value you wouldn't do this with String concatenation but by using patterns on text field. add for each field in the properties panel a patter such as R #,##0.00.
if it has to be in a single field you'd need to add an expression to actually format the numbers in the desired way such as for example: "R" + new DecimalFormat("#,##.00").format($F{Totalt}) + " (R" + new DecimalFormat("#,##.00").format($F{Totalp}) + ")"
You can use the FORMAT function to have thousand separator.
FORMAT({totalamount} +{totprobamount},2)
This column become String column so you have to add this column separately , you cant use same column for integer value. Where 2 is for up to 2 decimal value.
