SQL syntax inside VBA code

Is there any specific way to put SQL statements inside VBA code? I would like the SQL query to fit into VBA code, but if I do this, the query doesn't work. The same query works fine if I put the query statements in Range ("A1") and reference it in the code. Is there a way to build the query inside VBA code to make it work fine? The problem comes up especially when I add a sentence WHERE

.

Sub CreateQueryTableWithParameters()
    Dim qryTable As QueryTable
    Dim rngDestination As Range
    Dim strConnection As String
    Dim strSQL As String

    With Sheets("Sheet1")
        .Activate
        .Range("A:BY").Clear

    End With


' Define the connection string and destination range.
strConnection = "ODBC;DSN=RDBWC;UID=;PWD=;DBALIAS=RDBWC;"

Set rngDestination = Sheet1.Range("A1")
' Create a parameter query.
strSQL = "SELECT *"
strSQL = strSQL & "FROM pdb2i.DI_NOS_OST_MVT_01"
strSQL = strSQL & "WHERE COR_ID <> '90003'"

' Create the QueryTable.
Set qryTable = Sheet1.QueryTables.Add(strConnection, rngDestination)

' Populate the QueryTable.
qryTable.CommandText = strSQL
qryTable.CommandType = xlCmdSql
qryTable.Refresh False

    With Columns("D:D")
        .NumberFormat = "_(* #,##0.00_);_(* (#,##0.00);_(* ""-""??_);_(@_)"
        .AutoFit
    End With

    With Columns("H:J")
        .AutoFit
    End With

    Rows("1:1").Select
    Selection.AutoFilter

    Columns("H:H").ColumnWidth = 5
    Columns("I:I").ColumnWidth = 5
    Columns("J:J").ColumnWidth = 5
    Columns("M:M").ColumnWidth = 5.14
    Columns("N:N").ColumnWidth = 4

End Sub

      

        
        
        
      

    

I would like to add that I tried with [] parentheses and it still doesn't work

strSQL = "SELECT *"
strSQL = strSQL & "FROM pdb2i.DI_NOS_OST_MVT_01"
strSQL = strSQL & "WHERE [COR_ID] <> '90003'"
