I use this to create table , works ok
        mystring = "DSN=BIAPRO"          
        dbconn.Open mystring '
        adocat.ActiveConnection = dbconn
        On Error GoTo NoExist                'IF NOT IN TABLE not to delete thus
        klant$ = "MUT01"
        dbconn.Execute ("DROP TABLE " & klant$)

NoExist:
'======
    On Error GoTo Foutje
    strSQL = "CREATE TABLE " & klant$ & "("
    strSQL = strSQL & "MutRecord identity,"
    strSQL = strSQL & "MutYear char(2) NOT NULL,"
    strSQL = strSQL & "MutKlant char(3) NOT NULL,"
    strSQL = strSQL & "MutBoek char(2) NOT NULL,"
    strSQL = strSQL & "MutStuk char(6) NOT NULL,"
    strSQL = strSQL & "MutDate char(6) NOT NULL,"
    strSQL = strSQL & "MutPlace char(1) NOT NULL,"
    strSQL = strSQL & "MutRek char(4) NOT NULL,"
    strSQL = strSQL & "MutBtwFlag char(1) NOT NULL,"
    strSQL = strSQL & "MutBedrag FLOAT NOT NULL,"
    strSQL = strSQL & "MutBtw FLOAT NOT NULL,"
    strSQL = strSQL & "MutReden char(55) NOT NULL,"
    strSQL = strSQL & "wenkilos real NOT NULL,"
    strSQL = strSQL & "MutNewkey char(13) NOT NULL,"
    strSQL = strSQL & "FREEMORE char(151) NOT NULL)"
    dbconn.Execute (strSQL)                 '   ctreate tabel first


but then i need to create index, I do like this in 3 steps

 strSQL = "CREATE UNIQUE INDEX MutRecord ON MUT01 (MutRecord)"
 dbconn.Execute (strSQL)
'''GIVES ERROR  ""

 strSQL = "CREATE INDEX MutNewkey ON  MUT01 (MutNewkey)"
 dbconn.Execute (strSQL)
'''GIVES ERROR  ""

 strSQL = "CREATE INDEX MutBoek  ON  MUT01 (MutBoek)"
 dbconn.Execute (strSQL)
'''GIVES ERROR  ""

What error?  
You probably don't need to create the key on MutRecord since the field is an Identity and the field should already have an index.  

If you run the queries through PCC, do they work?

Since I could create the table in my source, after that i entered manualy the index using the pervasive console,
BUT!  i have mut01  upto mut99  and preferre not to do this by hand 99 times

Fyi -- since both field names and index names are stored in the same table (X$File), you cannot have indices with the same names as fields.

I echo Mirtheil's sentiment that you shouldn't need the first one, because of the Field type.

Do you have a plan for Continuity?

It's inevitable. People leave organizations creating a gap in your service. That's where Percona comes in.

skipped the 1st index, then got the attached error number
 strSQL = "CREATE INDEX MutNewkey ON  MUT01 (MutNewkey)"
 dbconn.Execute (strSQL)

Did you try changing the index name yet?  Add a prefix like "I_" to the start of the index name to make it unique.

Thanks again Bill,
