Writing Parameterized Queries
You can create dynamic spreadsheets by referencing cells in your SQL statement. The add-in executes the statement as a parameterized query. As you change the values in the sheet the add-in executes a new query.
Creating Searchable Spreadsheets
Use a parameterized SELECT WHERE query to create a spreadsheet that dynamically filters the data as you edit cells. The following filter criteria references the @InputSheet!A2 parameter -- cell A2 of the sheet InputSheet.
SELECT Id, Column1 FROM SampleTable_1 WHERE Column2 = @InputSheet!A2
Defining Optional and Required Parameters
When you prefix a parameter with @@, empty values in the referenced cell do not affect the query (i.e. any condition that refers to a cell with an empty value is removed).
In the following query, Column1 is an optional search parameter, but Column2 must be specified.
SELECT * FROM SampleTable_1 WHERE Column2 = @InputSheet!A2 AND Column1 = @@InputSheet!A3
Dynamic Table References
You can dynamically reference a table in a query by prefixing the cell reference with @@@. The following query will read the value from cell A1 on the InputSheet sheet and use that for the table name when executing the request.
SELECT * FROM @@@InputSheet!A1
Writing Other Search Conditions
By default, the add-in reports a match if the Outreach column contains the cell value. For example if the referenced cell has the value 'Bob', then the equivalent SQL predicate is:
LIKE '%Bob%'
You can execute starts-with and ends-with searches by adding a '%' to the cell value:
InputSheet!A2 Cell | Query | Equivalent Predicate |
'Bob' | SELECT * FROM SampleTable_1 WHERE Column2 LIKE @InputSheet!A2 | LIKE '%Bob%' |
'%Bob' | SELECT * FROM SampleTable_1 WHERE Column2 LIKE @InputSheet!A2 | LIKE '%Bob' |
'Bob%' | SELECT * FROM SampleTable_1 WHERE Column2 LIKE @InputSheet!A2 | LIKE 'Bob%' |
