Tosdata
This function returns a string value containing an SData where syntax corresponding to a Sage X3 valid condition.
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.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 expression
MY_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'"
This function only supports the following subset of the Sage X3 syntax:
find, pat, mod, left$, right$, mid$, seg$, tolower, toupper, ascii, chr$, abs, arr, year, day, monthExpressions that are not based on unary expressions are not accepted and trigger an error. The following table provides incorrect syntaxes and the correct equivalent syntaxes:
| Incorrect syntax | Correct syntax |
|---|---|
| pat(NAME,"*A*") | pat(NAME,"*A*")<>0 |
| find(NAME,"A","B","C") | find(NAME,"A","B","C")<>0 |
| AMOUNT | AMOUNT<>0 |
