Built-in Functions → decode

decode() is a conditional statement that enables you to add the procedural if-then-else logic to a query. decode() compares an expression against the search value. If the field value matches the caseValue, then the function returns the thenValue or else it returns the elseValue.

You can compare multiple values against the field value and return a thenValue for each matching result. The decode() statement will compare each field value, one by one.


decode(field, caseValue, thenValue, ..., elseValue)

The following table illustrates the decode() conditional statement parameters:

fieldThe input field value to compare
caseValueThe value compared against the field value
thenValueThe value returned as a result for matching codes, if the field value is equal to caseValue.
elseValueThe value returned as a result for non-matching codes, if the field value is not equal to caseValue.

To compare multiple values, use the following decode() statement: decode(field, caseValue, thenValue, caseValue, thenValue, elseValue).


String, int, double, or long representing the thenValue and elseValue in the column.


This example maps the Product ID: 16 with “Electronics”, 18 with “Hardware”, 136 with “Photo”, and maps all other Product ID values with "Other”.


The above decode() statement is equivalent to the following if-then-else statement:

result := 'Electronics';
result := 'Hardware';
result := 'Photo';
result := 'Other';

The following table illustrates the output of the decode() query:

Use the following steps for detailed instructions on how to use the decode() conditional statement:


In the Cluster Management Console (CMC), create a tenant that includes Sample Data. The Sample Data includes the SALES schema.

  • In the Navigation bar, select the Content tab, and then select + New → Add Dashboard.
  • In the Add Dashboard dialog, for Name, enter Product Dashboard, and then select Add.
  • In the Action bar, select + (add icon), or select + Add Insight.
  • In the Insight panel, select Listing Table or V.
  • In Tables, select Pivot Table.
  • In the Data panel, select Manage Dataset (+).
  • In the Manage Data Sets panel, in Tables, select SALES. Close the panel.
  • From the Data panel, drag and drop the following columns to the respective tray:
    • From the PRODUCTS table, drag and drop Product to the Row tray.
    • From the SALES table, drag and drop Product Id to the Row tray.
    • From the SALES table, drag and drop Year to the Column tray
    • From the SALES table, drag and drop Revenue to the Measure tray. In the Properties panel,
      • For Format, select Dollar Rounded.
    • From the SALES table, drag and drop Product Id to the Individual Filter tray. In the Filter panel,
      • For Operator, select In.
      • For Values, select 14, 16, 18, 31, and 136.
  • From the Data panel, drag and drop Add Formula to the Row tray.
  • The Formula Builder automatically opens:
    • In Search Functions, select the down arrow, and then select Conditional Statements.
    • Double-click the decode function, decode(field, caseValue, thenValue, elseValue), to add the formula to the editor.
    • In the Formula Editor,
      • Replace field with Product Id from the Data panel
      • Replace caseValue with 16
      • Replace thenValue with “Electronics”
      • Add two more caseValue, thenValue pairs:
        **18, "Hardware", 136, "Photo"**
      • Replace elseValue with “Other”
decode(SALES.SALES.PROD_ID, 16, "Electronics", 18, "Hardware", 136, "Photo", "Other")
  • Select Validate & Save.
  • In the Measure tray, double-click the New Formula pill and rename it to decode().
  • Name the insight Products.
  • In the Action bar, select Save.
