Tosdata

This function returns a string value containing an SData where syntax corresponding to a Sage X3 valid condition.

Syntax

STRING=toSData(VARIABLES, SDATA_VAR, EXPRESSION)

• VARIABLES is an array containing the variable names used in the condition.
• SDATA_VAR is an array containing the corresponding variable names used in the SData where resulting condition.
• EXPRESSION is a Sage X3 valid condition expressed in X3 syntax.

Example

Local Char VARS(20)(1..3), COLS(20)(1..3), MY_EXPRESSION(200),SDATA_EXPRESSION(200)VARS(1)="country" : VARS(2)="city" : VARS(3)="total"COLS(1)="COUNTRYCODE" : COLS(2)="CITYNAME" : COLS(3)="AMOUNT"# Transform the expressionMY_EXPRESSION="find(CITYNAME,'London','Paris')<>0 and (AMOUNT>=1 and AMOUNT<=100) and COUNTRYCODE<>'BE'"SDATA_EXPRESSION=toSData(COLS,VARS,MY_EXPRESSION)# The contents of SDATA_EXPRESSION is now:# "(city in 'London','Paris') and (total between 1 and 10) and country ne 'BE'"
