Hi,
We use database functions in our application.
Today I want to use a float4/real Parameter for the first time. You can
see a sample in in_test4.
Float8/double-parameters run fine.
The test.sql creates a small test database.
The Float4Test.java contains the code sample, which throws the following
exception.
| Hint: No function matches the given name and argument types. You
| might need to add explicit type casts.
| Position: 8
| at org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:2062)
| at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1795)
| at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:257)
| at org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Statement.java:479)

| at org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Statement.java:360)
| at Float4Test.main(Float4Test.java:24)
If I call
| Select in_test4(0.4) ;
in psql, everything runs fine.
Is it a bug in the JDBC-driver?
I use postgres 8.4.0 and driver postgresql-8.4-701.jdbc4.jar.
Ciao
