GETFILTERS Function (Query)

Returns the filters that are applied to all columns in the query.

The following code shows the syntax of the GETFILTERS function. Query is a variable of the Query data type that specifies the query object.

Filter := Query.GETFILTERS

Return Value

Type: Text

A text string that lists the filters that are set on all columns of the query. If there are no applicable filters, then an empty string is returned.

Remarks

The GETFILTERS function returns the filters that are currently set for all data columns and filter rows by the SETFILTER Function (Query) function, SETRANGE Function (Query) function, and the ColumnFilter Property in Query Designer. The GETFILTER function does not return filters that are set on a column's source field by the DataItemTableFilter Property in Query Designer or global filters that are set by the FILTERGROUP function.

You can call the GETFILTERS function multiple times and at any point in the code. If you call the GETFILTERS function before the first SETFILTER or SETRANGE function call, then the GETFILTERS function returns only filters that are set by the ColumnFilter property of the columns.

Filters that are set by the SETFILTER function and SETRANGE function are applied to a query when the query is opened by using a call to the OPEN, the SAVEASXML, or SAVEASCSV functions. You must consider the location of the GETFILTERS function with respect to these functions to obtain the results that you want. For example, in the following two code examples, the GETFILTERS function will return the filter set by the SETFILTER function call. However, in the first example, the filter has been applied to the query dataset; in the second example, the filter has not been applied.

Query.SETFILTER(Column, String);
Query.OPEN; 
Query.GETFILTERS;
Query.READ;

Query.OPEN; 
Query.SETFILTER(Column, String);
Query.GETFILTERS;
Query.READ;

Example

The following C/AL code example demonstrates how to use the GETFILTERS function on a query. The example code sets filters on a query column, and then displays a message when the query is run that indicates the filter on the column.

This example requires that you do the following:

1. Create a query called Customer_SalesQuantity that has the following characteristics:

   • Links table 18 Customer with table 37 Sales Lines from the CRONUS International Ltd. demonstration database.

   • Includes columns for the Name and No. fields from the Customer table and the Quantity field from Sales Lines table.

     For step-by-step instructions for creating this query, see Walkthrough: Creating a Query to Link Two Tables.

   • The ColumnFilter property of the Quantity column is set with a filter that includes values greater than 10.

2. Create the following C/AL variables and text constant in the object that will run the query.

   Variable name	DataType	Subtype
   MyQuery	Query	Customer_SalesQuantity
   MyFilters	Text	Not applicable

   Text constant name	ENU Value
   Text000	The filters are as follows: %1

The following C/AL code runs the query and displays a message that contains the filter that is set on a query column. You can add the code to the OnRun trigger of a codeunit, and then run the codeunit to see the results.

// Sets a filter to display only sales quantities greater than 10. This overwrites the value of ColumnFilter property.
MyQuery.SETFILTER(Quantity, '>10');
// Sets a filter to display the columns with the value Selangorian Ltd. only.
MyQuery.SETFILTER(NAME, 'Selangorian Ltd.');
// Runs the query and applies the filter.
MyQuery.OPEN;
// Returns the filters that are on the Quantity column and displays the filters in a message.
MyFilters := MyQuery.GETFILTERS;
MESSAGE(Text000, MyFilters);

Running the code returns the following message:

The filters are as follows: Quantity > 10, Name = Selangorian Ltd.
