The creation of XYZ* tables would not be needed.
-Tom.
In MS Access I have a routine as follows that interrogates all the
tables in the database looking for a certain value.
I am looking for similar routine for SQL Server. It needs to to be
run at the server and not link to the tables.
First the MS Access routine runs to create three tables. XYZTables,
XYZFields, and XYZResults and populates XYZTables and XYZFields.
XYZFields is needed for the Interrogation routine that follows:
Public Sub DocumentTables()
Dim db As DAO.Database, tbl As DAO.TableDef, fld As DAO.Field
Dim rstTable As DAO.Recordset, rstField As DAO.Recordset
Dim t As String, strQuery As String
Dim strTableSet As String, strFieldSet As String
strSQL = "CREATE TABLE XYZTables " & _
"(TableName TEXT CONSTRAINT " & _
" PrimaryKey PRIMARY KEY, " & _
" TableRecords Number) "
CurrentDb.Execute strSQL, dbFailOnError
strSQL = "CREATE TABLE XYZFields " & _
"(TableName CHAR, " & _
"FieldName CHAR, " & _
"DataType CHAR, " & _
"DataSize Number, " & _
"FieldDesc CHAR, " & _
"SearchValue CHAR) "
CurrentDb.Execute strSQL, dbFailOnError
strSQL = "CREATE TABLE XYZResults " & _
"(TableName CHAR, " & _
"FieldName CHAR, " & _
"DataType CHAR, " & _
"DataSize Number, " & _
"FieldDesc CHAR, " & _
"SearchValue CHAR) "
CurrentDb.Execute strSQL, dbFailOnError
strTableSet = "xyzTables"
strFieldSet = "xyzFields"
DoCmd.SetWarnings False
DoCmd.RunSQL "DELETE * FROM [" & strTableSet & "];"
DoCmd.RunSQL "DELETE * FROM [" & strFieldSet & "];"
DoCmd.SetWarnings True
Set db = CurrentDb
Set rstTable = db.OpenRecordset(strTableSet, dbOpenDynaset)
Set rstField = db.OpenRecordset(strFieldSet, dbOpenDynaset)
Debug.Print
For Each tbl In db.TableDefs
Debug.Print tbl.Name
If tbl.Attributes = 0 Then
With rstTable
.AddNew
.Fields("TableName") = tbl.Name
.Fields("TableRecords") = tbl.RecordCount
On Error Resume Next
.Fields("TableDesc") =
tbl.Properties("Description").Value
On Error GoTo 0
.Update
End With
For Each fld In tbl.Fields
'add new record for each field in each table,
containing
'table, field, data type of field
With rstField
.AddNew
.Fields("TableName").Value = tbl.Name
.Fields("FieldName").Value = fld.Name
.Fields("DataType").Value =
GetFieldDataType(fld.Type)
.Fields("DataSize").Value = fld..Size
On Error Resume Next
.Fields("FieldDesc").Value =
fld.Properties("Description").Value
On Error GoTo 0
.Update
End With
Next fld
End If
Next tbl
Debug.Print
rstField.Close
rstTable.Close
Set fld = Nothing
Set tbl = Nothing
Set db = Nothing
End Sub

_

db.Execute strSQL, dbFailOnError
End If

You're right about the tables -- actually I'm really not sure why it's
in there at all. It's not used. xyzFields is the one that is used
and hat is definitely needed. But the effort here is to use SQL
Server exclusively on the same machine.
If you're really not sure what I am asking: Say you are looking for
the string "abc123" and you need to look in all the tables and columns
for that value. I have the routine to do so in Access as posted. I
am looking for a way to do it using SQL Server. Appriciate any
suggestions!
