return true, if lower/uppercase checked by the current connected server
Example
The item "RM" is stored in the database
// MSSQL
sqlca.select "ItemName" from "OITM" where "ItemCode"='rm'
// return the item name
// HANA
sqlca.select "ItemName" from "OITM" where "ItemCode"='rm'
// return sqlca.sqlcode=100 (not found), because hana check lower/uppercase
with the property uppercase you can check, if current server check this
<sqlca.uppercase> : HANA: true, MSSQL: false
