SAP HANA ROWID (SAP HANA “$rowid$“)

SAP HANA ROWID:

范例一： Select  "$rowid$",* from EMP where "$rowid$" >6  and "$rowid$" < 10

范例二：

SELECT "$rowid$" as ROW_ID,* FROM EMP

注意：只能使用"$rowid$",使用 $rowid$    "$ROWID$"都是错误的语法。 

错误语法：

错误范例一:Select "$rowid$",* from EMP where "$rowid$" >6 and $rowid$ < 10
