Re: PreparedStatements, LIKE and the % operator

That was a typo. Sorry. I wasn't using '=' at all.

That's what I was doing. The driver gives this error:

-----------------------------
org.postgresql.util.PSQLException: The column index is

org.postgresql.core.v3.SimpleParameterList.bind(SimpleParameterList.java:52)

    at
org.postgresql.jdbc2.AbstractJdbc2Statement.setString(AbstractJdbc2Statement.java:1227)
....etc........
--------------------------------

I hacked around a bit and finally said:

.... bar like ? and foo like ?

ps.setString(1, "%" + myvalue + "%")
ps.setString(2, "%" + my_other_value + "%")

That worked but it's a bit counter-intuitive.
