Hi

so 23. 11. 2024 v 16:01 odesílatel <ma.sao@msa.hinet.net> napsal:

I get get this same error

syntax error at or near "$1" at character 15

if I feed "const char *command" with the following texts.

SET TIME ZONE $1
SET TIME ZONE $1::TEXT

For some reasons, I can not add quotes around $1 as follows.

SET TIME ZONE '$1'
SET TIME ZONE '$1'::TEXT

Statements like "SELECT ... WHERE $1=..." have been working flawlessly.

It looks like PQexecParams doesn't handle statement with "SET ... $1". 

Are there workarounds for me or PQexecParams needs improvement?

This statement has no plan, and then doesn't support parametrization.


SELECT set_config('timezone', $1, false)

Regards

Pavel


 

Thank you!
