SQL-02120: First and second arguments to SQLRCN both null

SQL-02120: First and second arguments to SQLRCN both null
Cause: Both the first and second arguments to sqlrcn were null. An HSTDEF must be passed into SQLRCN in either the form of an OCI lda (first argument) or as an HSTDEF pointer itself (second argument).
Action: Pass in either an OCI LDA or an HSTDEF, but not both. *Note: This error *msg* is never actually used. The error *number* is used, given as the return value of sqlrcn if this error occurs.

SQL-02120：SQLRCN的第一个和第二个参数都为空,
.原因： sqlrcn的第一个和第二个参数都为null。HSTDEF必须以OCI lda（第一个参数）的形式或作为HSTDEF指针本身（第二个参数）的形式传递到SQLRCN中。,
.行动：通过OCI LDA或HSTDEF，但不能同时进入。*注意：此错误* msg *从未实际使用。如果发生此错误，则使用错误* number *作为sqlrcn的返回值。,
