Pass Variables in SQL WHERE clause

Pass Variables in SQL WHERE clause

Pass Variables in SQL WHERE clause

(OP)
I need to be able to run a SQL query that will look something like this:
SELECT * FROM [TABLE] WHERE Field= (variable)
That is pass a variable to the WHERE clause.
assuming that I have a variable already present and that it holds the value of the a "field".
What is the CORRECT SYNTAX?
Any help will be great
Thanks
Alexis

RE: Pass Variables in SQL WHERE clause

Hi alexisa,

Below is a sample code:

Dim strWhere as string
Dim strSQL as string

strWhere = text1.text 'Take in criteria from text box

strSQL = "SELECT * FROM [TABLE] WHERE Field="
strSQL = strSQL & strWhere

............


Obviuosly you need to open a connection to a database and bring back a recordset. If you are not sure how to do this let me know and I'll post the code.

RE: Pass Variables in SQL WHERE clause

I believe that the syntax is different for string vs. numeric fields (possibly dependent on the database).

For numeric fields:
"Select * From ..... Where myFld = " & NumericField

For string fields:
"Select * From ..... Where myFld = '" & StringField & "'"
where you're surrounding your data with single quotes.

For date fields (and Access):
"Select * From ..... Where myFld = #" & DateField & "#"

RE: Pass Variables in SQL WHERE clause

VB400 is correct, you do need the double quotes around the string. However, the # sign is not needed for dates (outside of access)
