retrieve a record from a dataset?????

[DaveF]

How can I retrieve display_names





Dim custDS As DataSet = New DataSet

Dim mySQL, mySQL2, mySQL3 As String

mySQL = "SELECT id,GBL_NO,TCN,TRAC_NO,SHIP_NAME, CAT FROM(SELECT
id,GBL_NO,TCN,TRAC_NO,CAT,SHIP_NAME, ROW_NUMBER() OVER ( PARTITION BY TCN
ORDER BY TCN, TRAC_NO, CAT ) as row_num FROM TRACK.DTTS WHERE (CDATE BETWEEN
TO_DATE('7/18/2003','MM/DD/YYYY') AND TO_DATE('7/20/2004','MM/DD/YYYY')) AND
((gbl_no= qqqqqqqqqq)) ) WHERE row_num = 1 ORDER BY TCN"

' mySQL = "SELECT id,GBL_NO,TCN,TRAC_NO, CAT FROM(SELECT
id,GBL_NO,TCN,TRAC_NO,CAT, ROW_NUMBER() OVER ( PARTITION BY GBL_NO ORDER BY
GBL_NO, TCN, TRAC_NO, CAT ) as row_num FROM TRACK.V_LATESTPNTDTTS WHERE
(CDATE BETWEEN TO_DATE('7/18/2003','MM/DD/YYYY') AND
TO_DATE('7/20/2004','MM/DD/YYYY')) AND ((SCACNAME LIKE 'T%')) or ((SCACNAME
LIKE 'p%'))) WHERE row_num = 1 ORDER BY GBL_NO"

mySQL2 = "SELECT TCN,CDATE FROM TRACK.DTTS WHERE (CDATE BETWEEN
TO_DATE('7/18/2003','MM/DD/YYYY') AND TO_DATE('7/20/2004','MM/DD/YYYY')) AND
((gbl_no= 'A-1003601-01')) ORDER BY tcn,id"

mySQL3 = "SELECT display_names FROM TRACK.V_RPTTRACK WHERE ID = 6"

Dim myTable As DataTable

myTable = myData.GetTableData(mySQL)

custDS.Tables.Add(myTable)

custDS.Tables(0).TableName = "Table1"

myTable = myData.GetTableData(mySQL2)

custDS.Tables.Add(myTable)

custDS.Tables(1).TableName = "Table2"

myTable = myData.GetTableData(mySQL3)

custDS.Tables.Add(myTable)

custDS.Tables(2).TableName = "Table3"

Me.DataBind()

the dataset can be addressed like a matrix
ds.tables[0].rows[row][col].tostring() so you can use row,col co-ordinates
to find your item
