Here is my query that results in a syntax error:
SELECT *
FROM account_invoice,sale_order
WHERE sale_order.name LIKE %account_invoice.origin%
The account_invoice.origin field contains the text of sale_order.name, plus other text as well, so I need to match sale_order.name string anywhere in the account_invoice.origin string.
I'm using PostgreSQL 8.4.
Try this
SELECT *
FROM account_invoice,sale_order
WHERE sale_order.name LIKE '%' || account_invoice.origin || '%'
%
needs single quote because the pattern is a string.
||
is the operator for concatenation.
