Currently I have two org tables, and want to use the data stored in both of them to change the second table. Reading the tables in a source block is no problem, but what do I have to do to write fields of a table?

I’m experiancing a problem when trying to link to tables in the database expert. The two fields that link the tables have exactly the same information except one table always has an additional space. For example;
Table 1 = Multivitamin/Tablets
Table 2 = Multivitamin//Tablets
‘/‘ are representing spaces
Formulas won’t help (e.g. extractstring etc) as it’s the tables themselves I need to link together
This is preventing me from retrieving the information I need. Any advice on how I can get around this?
There are some ways to come across this:
Consider using a command as datasource instead of tables. When writing the query of the command you can define the join condition yourself.
If you have access to the data source, you could add a calculated field to the tables to contain the normalized field values and then use these for linking in CR.
Alternatively, one could create views in the database, either adding normalized "linking fields" or providing the joined tables results.
If it's only a few rows in CR, you could consider using SQL fields or subreports to retrieve data from Table 2.
I have a dataset based on a csv file. This exposes a data as follows:
Name,Age
John,23
I have an Azure SQL Server instance with a table named: [People]
This has columns
Name, Age
I am using the Copy Data task activity and trying to copy data from the csv data set into the azure table.
There is no option to indicate the table name as a source. Instead I have a space to input a Stored Procedure name?
How does this work? Where do I put the target table name in the image below?
You should DEFINITELY have a table name to write to. If you don't have a table, something is wrong with your setup. Anyway, make sure you have a table to write to; make sure the field names in your table match the fields in the CSV file. Then, follow the steps outlined in the description below. There are several steps to click through, but all are pretty intuitive, so just follow the instructions step by step and you should be fine.

You can add records into the SQL Database table directly without stored procedures, by configuring the table value on the Sink Dataset rather than the Copy Activity which is what is happening.
Have a look at the below screenshot which shows the Table field within my dataset.
I need to update a mapping table in postgresql, but of course it won't allow me to replace/drop the original table as there are dependencies.
The error message details does list the dependent views, but I'd like to generate a list programmatically so that I can make temp views while I drop my original mapping table and migrate the views back afterwards.
Prefer not to do this in SQL Shell incidentally. Any pointers would be much appreciated.
I'm using Filemaker Pro 12 and I was wondering if there is a way of creating a template for tables. There are a number of fields I'm placing in my tables that are identical utility-fields like modification time-stamp, active/inactive flags, etc. I was hoping there was a way that I could define the skeleton of each table somehow instead of having to manually add these identical fields every time.
If you are using the Advanced version, you can copy&paste fields among tables/files.
Using the regular version, you can import records from your "default" table and specify [New Table...] as the target table. This will recreate the source table's structure in the target file. The source table does not have to contain any records for this to work.
To expand a little bit on michael-hor257k's answer, if you're using FileMaker Pro Advanced, a good practice is to create a "Default" table that has your core utility fields. When you want to make a new table in Manage Database, instead:
Highlight the Default table,
Copy & Paste the table, then
Rename the new table.
This may be a very simplistic question, so apologies in advance, but I am very new to database usage.
I'd like to have Postgres run its full text search across multiple joined tables. Imagine something like a model User, with related models UserProfile and UserInfo. The search would only be for Users, but would include information from UserProfile and UserInfo.
I'm planning on using a gin index for the search. I'm unclear, however, on whether I'm going to need a separate tsvector column in the User table to hold the aggregated tsvectors from across the tables, and to setup triggers to keep it up to date. Or if it's possible to create an index without a tsvector column that'll keep itself up to date whenever any of the relevant fields in any of the relevant tables change. Also, any tips on the syntax of the command to create all this would be much appreciated as well.
Your best answer is probably to have a separate tsvector column in each table (with an index on, of course). If you aggregate the data up to a shared tsvector, that'll create a lot of updates on that shared one whenever the individual ones update.
You will need one index per table. Then when you query it, obviously you need multiple WHERE clauses, one for each field. PostgreSQL will then automatically figure out which combination of indexes to use to give you the quickest results - likely using bitmap scanning. It will make your queries a little more complex to write (since you need multiple column matching clauses), but that keeps the flexibility to only query some of the fields in the cases where you want.
You cannot create one index that tracks multiple tables. To do that you need the separate tsvector column and triggers on each table to update it.
