Hi All, I am having a problem creating a recursive query. DB2 returns an invalid reference error (SQL0346): http://publib.boulder.ibm.com/infocenter/db2luw/v9/index.jsp?topic=/com.ibm.db2.udb.msg.doc/doc/sql0346.htm Based on this error code, the problem seems to be a result of doing a recursive query! ... Which is exactly what I need! According to IBM documentation this syntax should work and preform a recursive style query: http://publib.boulder.ibm.com/infocenter/db2luw/v8/index.jsp?topic=/com.ibm.db2.udb.doc/admin/r0000879.htm The error refers to where it says "FROM RPL" on line 4 ... (The part that makes the query recursive) WITH RPL (NODEID, PARENT, NAME) AS ( SELECT ROOT.NODEID, ROOT.PARENT, ROOT.NAME FROM MNUNODES ROOT WHERE NODEID = :NODEID UNION ALL SELECT CHILD.NODEID, CHILD.PARENT, CHILD.NAME FROM RPL, MNUNODES CHILD WHERE CHILD.PARENT=RPL.NODEID ) SELECT DISTINCT NODEID, PARENT, NAME FROM RPL One thing to note is that the data shall never have a structure that may cause an infinite loop. Does anyone have any suggestions? Regards, Milan Zdimal
