Why SCALE=4? Wouldn't that fix 4 decimal placement? I'm am looking for a SCALE that will allow any number with any decimal placement.

I have a link generator written that is reading Source (Oracle) tables and that uses the %Library.ResultSet class. for each it gets column name, type, maxsize, precision, lais, readonly, required & data type name and builds Cache Linked Table.

Are you referring to this logic where I need to apply scale? I do not see any SCALE references in logic.

 if (jdbc) {
  s rs= ##class(%Library.ResultSet).%New("%GTWCatalog:SQLFieldsJ")
 } else {
  s rs= ##class(%Library.ResultSet).%New("%GTWCatalog:SQLFields")
 }
 s sc = rs.Execute(gateway, table, schema)
 if ($$$ISERR(sc)) {
  d $system.OBJ.DisplayError(sc)
  quit sc
 }
 s tname = schema _ "." _ table
 s cols = ""
 while rs.Next() {
  s externalcolumnname=rs."COLUMN_NAME",
    columnname = externalcolumnname,
    columntype=rs.DATATYPE,
    columnmaxsize=rs."COLUMN_SIZE",
    columnprecision=rs."DECIMAL_DIGITS",
    columnalias="" /* defaults to externalcolumnname */,
    readonly=0 /* hardcoded */,
    required='rs.NULLABLE,
    notused="",
   datatypename=rs."DATATYPE_NAME"
   if prikey="",(externalcolumnname["_cd")!(externalcolumnname["_id") SET prikey=externalcolumnname
  s col=$LTS($LB( externalcolumnname,
     columnname,
    columntype,
    columnmaxsize,
    columnprecision,
    columnalias,
    readonly,
    'required,
    notused,
    datatypename ),"^")
  s cols = cols_$LB(col)
 }
 s cols=$LTS(cols,"@")
 d rs.Close()
 

Hi Robert,

When I review the existing DDL Mapping for NUMBER, the datatype states: %Library.Numeric(SCALE=0)

This does not make any sense my generated SQL Table code(.cls & .int) is validating with EXTERNALSQLTYPE=2 and $isvalidnum(%val,2,,)

I thought SCALE=0 allowed any decimal value but it appears somewhere else there is logic that is defaulting this SCALE to 2.
