Hey.
This is the method I wrote to do thios for POSTGRESql:
public String getDataTypeName( int type, int size, int decimals )
{
switch (type)
{
case Types.BIT: return "BOOLEAN";
case Types.TINYINT: return "SMALLINT";
case Types.BIGINT: return "INT";
case Types.LONGVARBINARY: return "LONG BYTE";
case Types.VARBINARY: return "VARCHAR(" + size + ") BYTE";
case Types.BINARY: return "CHAR(" + size + ") BYTE";
case Types.LONGVARCHAR: return "TEXT";
case Types.CHAR: return "CHAR(" + size + ")";
case Types.NUMERIC: return "DECIMAL(" + size + "," + decimals +
")";
case Types.DECIMAL: return "DECIMAL(" + size + "," + decimals +
")";
case Types.INTEGER: return "INT";
case Types.SMALLINT: return "SMALLINT";
case Types.FLOAT: return "FLOAT";
case Types.REAL: return "REAL";
case Types.DOUBLE: return "DOUBLE PRECISION";
case Types.VARCHAR: return "VARCHAR(" + size + ")";
case Types.DATE: return "DATE";
case Types.TIME: return "TIME";
case Types.TIMESTAMP: return "TIMESTAMP";
default: return "TEXT";
}
}
where the Types is the java.sql.Types class..
Hope that helps
Carl

Subject: [JDBC] Recommended Data Mappings
All,
I have been looking for a table that specifies the recommended mappings
for the internal PostgreSQL data types to Java data types. I can make a
good stab a most of them; however, would like to know the recommeded
ones. I have looked in the docs, and performed several searches on the
web to try and find; but alas, not success.
Any help would be appreciated.
TIA
