Error importing schema on DBMS ER

Question

When running the recommended import script on my Postgresql V17 database (Ubuntu 24)

Any help appreciated

Error is:

ERROR:  syntax error at or near "="LINE 1: SELECT COUNT(*) AS total FROM (SET enable_nestloop=0;SELECT …In statement:SELECT COUNT(*) AS total FROM (SET enable_nestloop=0;SELECT 'postgresql' AS dbms,t.table_catalog,t.table_schema,t.table_name,c.column_name,c.ordinal_position,c.data_type,c.character_maximum_length,n.constraint_type,k2.table_schema,k2.table_name,k2.column_name FROM information_schema.tables t NATURAL LEFT JOIN information_schema.columns c LEFT JOIN(information_schema.key_column_usage k NATURAL JOIN information_schema.table_constraints n NATURAL LEFT JOIN information_schema.referential_constraints r)ON c.table_catalog=k.table_catalog AND c.table_schema=k.table_schema AND c.table_name=k.table_name AND c.column_name=k.column_name LEFT JOIN information_schema.key_column_usage k2 ON k.position_in_unique_constraint=k2.ordinal_position AND r.unique_constraint_catalog=k2.constraint_catalog AND r.unique_constraint_schema=k2.constraint_schema AND r.unique_constraint_name=k2.constraint_name WHERE t.TABLE_TYPE='BASE TABLE' AND t.table_schema NOT IN('information_schema','pg_catalog')) AS sub

​@kerrya- Kindly separate the SET command from your query.First, run the command "SET enable_nestloop = OFF;" as a standalone statement.Then, execute your SELECT query in a separate step and give a try.----------------------------------------------------------------------------------In addition, you can also try using different syntax to set the parameter. Instead of the original command, use either "SET enable_nestloop TO OFF;" or "SET enable_nestloop = 'OFF';" as some PostgreSQL versions support "TO" instead of "=" for this purpose. If issues persist, try removing the semicolon and executing "SET enable_nestloop TO OFF".Keep us posted on the outcome!!Regards

Hi ​@kerryaSeems it is due to an incorrect use of SET enable_nestloop=0; within a SELECT statementTry running SET enable_nestloop = OFF; separately before executing the queryModify your script to separate the SET command from the SELECT statement, then give a try and keep us posted.Best Regards
