    Here is my original query string:

    String sql = "SELECT BSYDTAA.BSYPEMP.EMYLNM, BSYDTAA.BSYPEMP.EMYFNM,
    BSYDTAC.BPRPPCP.PCDEP4, BSYDTAC.BPRPPCP.PCLDDS, BSYDTAA.BSYPEMP.EMEMP# AS
    EMEMP, BSYDTAA.BSYPEMP.EMWPH# AS WPHONE FROM BSYDTAA.BSYPEMP,
    BSYDTAC.BPRPPCP WHERE BSYDTAA.BSYPEMP.EMHSP# = BSYDTAC.BPRPPCP.PCHSP# AND
    BSYDTAA.BSYPEMP.EMDEP4 = BSYDTAC.BPRPPCP.PCDEP4 AND (BSYDTAA.BSYPEMP.EMHSP#
    IN (1,5)) AND (BSYDTAA.BSYPEMP.EMDOT=0)";

    sql += " AND EMYLNM like ?";

    sql += " AND EMYFNM like ?";

    sql += " ORDER BY EMYLNM";

    Thanks

    Frank
