PostgreSQL error 42601- How we fix it

Syntax errors are really widespread though coding.

But, points go for a toss when it outcomes in web-site errors.

PostgreSQL error 42601 also happens due to syntax errors in the database queries.

At Bobcares, we usually get requests from PostgreSQL customers to repair errors as portion of our Server Management Solutions.

Nowadays, let’s verify PostgreSQL error in detail and see how our Help Engineers repair it for the shoppers.

How we repair the error?

Now let’s see how our PostgreSQL engineers resolve this error effectively.

Lately, 1 of our shoppers contacted us with this error. He attempted to execute the following code,

Develop OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS
$$
Start
WITH m_ty_individual AS (return query execute sql)
pick name, count[Need more assistance to solve PostgreSQL error 42601?- We’;ll help you.] from m_ty_individual exactly where name like '%a%' group by name
union
pick name, count[Need more assistance to solve PostgreSQL error 42601?- We’;ll help you.] from m_ty_individual exactly where gender = 1 group by name
Finish
$$ LANGUAGE plpgsql

&nbsp

But, this ended up in PostgreSQL error 42601. And he got the following error message,

ERROR: syntax error at or close to "return"
LINE 5: WITH m_ty_individual AS (return query execute sql)

&nbsp

Our PostgreSQL Engineers checked the problem and discovered out the syntax error. The statement in Line 5 was a mix of plain and dynamic SQL. In basic, the PostgreSQL query must be either completely dynamic or plain. For that reason, we changed the code as,

RETURN QUERY EXECUTE '
WITH m_ty_individual AS (' || sql || $x$)
Pick name, count[Need more assistance to solve PostgreSQL error 42601?- We’;ll help you.]::int FROM m_ty_individual Exactly where name LIKE '%a%' GROUP BY name
UNION
Pick name, count[Need more assistance to solve PostgreSQL error 42601?- We’;ll help you.]::int FROM m_ty_individual Exactly where gender = 1 GROUP BY name$x$

This resolved the error 42601, and the code worked fine.
