尝试使用查询从源中提取数据:
concat('select column_name from {$trytable} where table_name =',$scddimname)
声明的参数和分配的值都为:
scddimname string 'emp_scd'
trytable string'INFORMATION_SCHEMA.COLUMNS'
但是,错误
Error:
DF-DSL-001 - DSL stream has parsing errors
Line 9 Position 86: token recognition error at: '\n' - RunId: e93f18d2-cc0d-4b64-8336-15e75a5aaa22
看起来很麻烦!
