Exception occurs for hash character in Dollar quote with JPA - jpa

I am using Dollar quote (i.e. $xx$) for my query and getting Exception when the input has a hash character(#) inside.
select * from tbl_abc where col_x = $xx$#$xx$
^
The Exception is:
Internal Exception: org.postgresql.util.PSQLException: The column index is out of range: 1, number of columns: 0.
Error Code: 0
Call: select * from tbl_abc where col_x = $xx$?
bind => [1 parameter bound]
I can see there a ? character in the error message, but I didn't have that in my query. Here is my java code:
String query = "select * from tbl_abc where col_x = $xx$#$xx$";
Query nativeQuery = em.createNativeQuery(query, Abc.class);
List<Abc> abcList = nativeQuery.getResultList();
FYI: it works smoothly when I use '#' instead of $xx$#$xx$. Also my query runs nicely from the postgres console.
How can I escape that # character for Dollar quote from JPA?
I am using Java with Eclipselink and the database is Postgres.

Springboot JPA Cast numeric substring to string

I have a JPA/Springboot application backed by a Postgres database. I need to get a records that is equal to a substring passed back to the server.
For example:
Select * from dp1_attachments where TRIM(RIGHT(dp1_submit_date_dp1_number::text, 5)) ='00007'
This query works in PgAdmin, but not in the JPA #Query statement.
#Query("SELECT a.attachmentsFolder as attachmentsFolder, a.attachmentNumber as attachmentNumber, a.attachmentName as attachmentName, a.dp1SubmitDateDp1Number as dp1SubmitDateDp1Number,a.attachmentType as attachmentType, a.attachmentDate as attachmentDate, a.attachmentBy as attachmentBy "
+ "FROM DP1Attachments a WHERE TRIM(SUBSTRING(a.dp1SubmitDateDp1Number::text, 5 )) = :dp1Number")
I've also tried CASTing the parameter like this:
#Query("SELECT a.attachmentsFolder as attachmentsFolder, a.attachmentNumber as attachmentNumber, a.attachmentName as attachmentName, a.dp1SubmitDateDp1Number as dp1SubmitDateDp1Number,a.attachmentType as attachmentType, a.attachmentDate as attachmentDate, a.attachmentBy as attachmentBy "
+ "FROM DP1Attachments a WHERE TRIM(SUBSTRING(CAST(a.dp1SubmitDateDp1Number as string, 5 ))) = :dp1Number")
but the application won't even run, and returns an error that the query isn't valid.
If I make no attempt to cast it, I get an error that function pg_catalog.substring(numeric, integer) does not exist
UPDATE
I've also tried creating a native query instead but that also doesn't seem to work.
List<DP1AttachmentsProjection> results = em.createNativeQuery("Select * FROM dp1_attachments WHERE TRIM(RIGHT(CAST(dp1_submit_date_dp1_number as varchar),5)) =" + dp1Number).getResultList();
In place of varchar I have also tried string and text.
Errors come back similar to ERROR: operator does not exist: text = integer. Its like the CAST is being ignored and I'm not sure why.
I also tried the following as a native query:
em.createNativeQuery("Select * FROM dp1_attachments WHERE TRIM(RIGHT(dp1_submit_date_dp1_number::varchar),5)) =" + dp1Number).getResultList();
and get ERROR: syntax error at or near ":"
FINAL SOLUTION
Thanks to #Nenad J I altered the query to get the final working solution:
#Query(value = "SELECT a.attachments_Folder as attachmentsFolder, a.attachment_Number as attachmentNumber, a.attachment_Name as attachmentName, a.dp1_Submit_Date_Dp1_Number as dp1SubmitDateDp1Number,a.attachment_Type as attachmentType, a.attachment_Date as attachmentDate, a.attachment_By as attachmentBy FROM DP1_Attachments a WHERE TRIM(RIGHT(CAST(a.dp1_Submit_Date_Dp1_Number as varchar ), 5 )) = :dp1Number", nativeQuery = true)"
Default substring returns a string, so substring(integer data,5) returns a string. Thus no need for the cast.
#Query("SELECT * FROM DP1Attachments a WHERE TRIM(SUBSTRING(a.dp1SubmitDateDp1Number, 5)) = :dp1Number")
But I recommend in this case use native query like this:
Put this code in your attachment repository.
#Query(value="SELECT * FROM DP1Attachments AS a WHERE TRIM(SUBSTRING(a.dp1SubmitDateDp1Number, 5 )) = :dp1Number", nativeQuery=true)
Be careful with the column's name.

error syntax error at or near ":" for split_part () of createNativeQuery in spring boot for postgresql

I'm getting SQL exception while executing the query which contains
split_part() method as split_part(value::TEXT,':', 1).
String queryStr = " select split_part(value::TEXT,':', 1) from table";
Query query = entityManager.createNativeQuery(queryStr);
List results = query.getResultList();
ERROR 2020-02-10 14:54:37,926 [http-nio-7070-exec-1] 142 - ERROR: syntax error at or near ":"
Position: 855
Your obfuscation layer probably chokes on the :: operator. Use the cast() operator instead:
String queryStr = " select split_part(cast(value as text),':', 1) from table";
But why do you think you need the cast to begin with? If you are storing : characters that column, it is most probably a text (or varchar) column anyway and you don't need a cast at all.

The column index is out of range: 2, number of columns: 1 error while updating jsonb column

I am trying to update jsonb column in java with mybatis.
Following is my mapper method
#Update("update service_user_assn set external_group = external_group || '{\"service_name\": \"#{service_name}\" }' where user=#{user} " +
" and service_name= (select service_name from services where service_name='Google') " )
public int update(#Param("service_name")String service_name,#Param("user") Integer user);
I am getting the following error while updating the jsonb (external_group) cloumn.
### Error updating database. Cause: org.postgresql.util.PSQLException: The column index is out of range: 2, number of columns: 1.
### The error may involve com.apds.mybatis.mapper.ServiceUserMapper.update-Inline
I am able to update with the same way for non-jsonb columns.
Also if I am putting hardcoded value it's working for jsonb columns.
How to solve this error while updating jsonb column?
You should not enclose #{} in single quotes because it will become part of a literal rather than a placeholder. i.e.
external_group = external_group || '{"service_name": "?"}' where ...
So, there will be only one placeholder in the PreparedStatement and you get the error.
The correct way is to concatenate the #{} in SQL.
You may also need to cast the literal to jsonb type explicitly.
#Update({
"update service_user_assn set",
"external_group = external_group",
"|| ('{\"service_name\": \"' || #{service_name} || '\" }')::jsonb",
"where user=#{user} and",
"service_name= (select service_name from services where service_name='Google')"})
The SQL being executed would look as follows.
external_group = external_group || ('{"service_name": "' || ? || '"}')::jsonb where ...

Why do I get the error "called with 1 bind variables when 0 are needed" when I try to execute a query with DBI?

I'm trying to select some rows from a table (PostgreSQL) using the following code:
my $kadadbh = DBI->connect(
"dbi:Pg:dbname=$dbname;host=$host",
$dbuser,
$dbpasswd
);
my $subject_nar_sel= $kadadbh->prepare(
'SELECT * FROM subject WHERE SUBSTRING(CAST(id AS text),1,6) = "?";'
);
$nar=605812;
$subject_nar_sel->execute($nar);
But I get an error:
called with 1 bind variables when 0 are needed at ...
I get the same error when I swap the single and double quotes:
"SELECT * FROM subject WHERE SUBSTRING(CAST(id AS text),1,6) = '?';"
How can I fix this?
You current query is testing whether SUBSTRING(CAST(id AS text),1,6) matches the literal string suspiciously-named quoted identifier "?". So don't quote the ?, even when the bind parameter has a string type:
SELECT * FROM subject WHERE SUBSTRING(CAST(id AS text),1,6) = ?

intersystem cache C# query with datetime

When I use cache sql query in C# I'm getting an error:
SQLtext1 = "SELECT top 10 * FROM dbo.DAPPLICATIONSTAT where TIMESTAMP = '2015-02-01 00:00:00'"
I would like to use a where clause with a datetime filter.
I am using InterSystems.Data.CacheClient.dll to execute the query.
