Description

The subtraction operator computes the difference of two values.

The subtraction operator can be applied to INT or FLOAT columns or constants. The resulting column is of type INT if both input columns or constants are of type INT. In all other cases, the resulting column is of type FLOAT.

Syntax

SUB ( table.column1 , table.column2 )
table.column1 - table.column2

NULL handling

If one of the input values is NULL, the result is NULL as well.

Examples


[1] Subtract a constant INT value from a column of type INT:

Query
Column1
"Table1"."Column1" - 10
Input
Table1
Column1 : INT
1
2
3
4
Output
Result
Column1 : INT
-9
-8
-7
-6



[2] Subtract a constant FLOAT value from a column of type FLOAT:

Query
Column1
"Table1"."Column1" - 10.0
Input
Table1
Column1 : FLOAT
1.0
2.0
3.0
4.0
Output
Result
Column1 : FLOAT
-9.0
-8.0
-7.0
-6.0



[3] Subtract a constant FLOAT value from a column of type INT:

Query
Column1
"Table1"."Column1" - 10.0
Input
Table1
Column1 : INT
1
2
3
4
Output
Result
Column1 : FLOAT
-9.0
-8.0
-7.0
-6.0



[4] Subtract values of multiple INT and FLOAT columns:

Query
Column1
"Table1"."IntColumn1" - "Table1"."IntColumn2"
Column2
SUB ( "Table1"."IntColumn1" , "Table1"."FloatColumn1" )
Column3
"Table1"."FloatColumn1" - "Table1"."FloatColumn2"
Column4
"Table1"."IntColumn1" - "Table1"."IntColumn2" - "Table1"."FloatColumn1"
Column5
SUB ( "Table1"."IntColumn1" , "Table1"."IntColumn2" - "Table1"."FloatColumn1" )
Input
