Hello!
This issue really puzzles me beyond intrigue.
Why would this schema:
*SELECT 'CREATE DATABASE jme_test_database' WHERE NOT EXISTS (SELECT
FROM pg_database WHERE datname = 'jme_test_database')\gexec*
work when entered at the psql prompt, but not when passed as a parameter
in a JDBC method?
The bellow snip demonstrates the the creation of a String object with
same character string used in the PSQL#.
//CREATE DATABASE IF NOT EXISTS
//~~~~~~~~~~~~~~~~~~
*var s = new ***myString*(SELECT 'CREATE DATABASE jme_test_database'
WHERE NOT EXISTS (SELECT FROM pg_database WHERE datname =
'jme_test_database')\gexec);**
**
**stmt.executeUpdate(s.toString());*
However, this time PostgreSQL-15 complains with an error message saying :
*Exception in thread "main" org.postgresql.util.PSQLException: ERROR:
syntax error at or near "\"**
** Position: 122
*
For better clarification, I'd like to show the code to create the schema
inside Java/JDBC.

...
var sv = myString();
...
public final myString getCreateDatabase(myString s){
this.sv.setData("SELECT 'CREATE DATABASE ");
this.sv.append(s.toString());
this.sv.append("\'");
this.sv.append("WHERE NOT EXISTS (SELECT FROM pg_database WHERE
datname = ");
this.sv.append("\'");
this.sv.append(s.toString());
this.sv.append("\'");
this.sv.append(")\\gexec");
return sv;
}
Any help would be very much appreciated.
Thanks in advance.
