To expand on what Dieter said.... How do you list the existing database elements? Within DBC.TVM, the field TABLEKIND has the following options: o) T = Table o) V = View o) M = Macro o) J = Journal Table o) I = Join Index Table o) P = Stored Procedure o) G = Trigger o) F = Scalar UDF o) A = Aggregate UDF o) N = Hash Index Table Within DBC.INDEXES, the field INDEXTYPES has the following options: J--> Join index K--> Primary Key N--> Hash Index P--> Non Partitioned Primary Q--> Partitioned Primary S--> Secondary V--> value ordered U--> Unique Constraint H--> Hash ordered All covering secondary O--> Value ordered all covering secondary I--> ordering column of a composite secondary index 1--> field1 column of a join or hash index 2--> field2 column of a join or hash index These can then be used to identify the various element definitions within Teradata. For example, to check for a Join Index, which is both a table and an index: /* check TVM */ sel dbase.databasename (FORMAT 'X(15)'), tvm.tvmname (FORMAT 'X(25)') from dbc.tvm,dbc.dbase where dbase.databaseid=tvm.databaseid and tvm.tablekind='I' order by 1,2; /* and INDEXES */ SEL DISTINCT dbase.databasename (FORMAT 'X(15)'), tvm.tvmnameI (FORMAT 'X(25)'), indexes.name (FORMAT 'X(15)'), indexes.IndexNumber (FORMAT 'zzz9') FROM dbc.indexes,dbc.dbase,dbc.tvm WHERE dbase.databaseid=indexes.databaseid and tvm.tvmid=indexes.tableid and indexes.indextype in ('J', '1', '2') ORDER BY 1,2; -dave.clark
