Juergen Kissner commented on DERBY-5788:
----------------------------------------
Hi,
Looking at the Java documentation
(http://docs.oracle.com/javase/1.4.2/docs/guide/jdbc/getstart/mapping.html#999493):
9.3.4 BOOLEAN
The JDBC type BOOLEAN, which is new in the JDBC 3.0 API, maps to a boolean in
the Java programming language. It provides a representation of true and false,
and therefore is a better match than the JDBC type BIT, which is either 1 or 0.
This part of the description refers to BOOLEAN; however, the last part of the
sentence explicitly mentions the values 0 and 1.
Going back to the original meaning of "bit" (binary digit), "bit" is a digit.
So it is at least unexpected if you cannot use the digits 0 and 1 (or string
representations of them) in
prepstmt.setObject(pos, val, java.sql.Types.BIT).

> Key: DERBY-5788
> URL: https://issues.apache.org/jira/browse/DERBY-5788
> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.8.2.2
> Environment: Windows 7 (All)
> Reporter: Radoslav Ivanov
>
> Scenario (on 10.8.2.2; with 10.5.1.1 the problem does not appear): when
> setting BIT from this example :
> rsSch.createTab("Bit_Tab",sqlp,conn);
> String sMaxBooleanVal = rsSch.extractVal("Bit_Tab",1,sqlp,conn); //value is
> “1“
> cstmt = conn.prepareCall("{call Bit_In_Min(?)}");
> cstmt.setObject(1,sMaxBooleanVal,java.sql.Types.BIT); //-> throws the
> exception below
> Exception (Problem with not supporting “0” and “1” for the type BIT;
> moreover, confusing message):
> java.sql.SQLDataException: Invalid character string format for type BOOLEAN.
