Parameters

  • ctype
    A templated parameter that is the data type.

  • nParam
    [in] The parameter number (offset from 1). Parameter 0 is reserved for return values. The parameter number is the index of the parameter based on its order in the SQL or stored procedure call. See SetParam for an example.

  • pParamName
    [in] The parameter name.

  • pData
    [out] The pointer to the memory containing the data retrieved from the buffer.

Return Value

For nontemplated versions, points to the memory containing the data retrieved from the buffer. For templated versions, returns true on success or false on failure.

Use GetParam to retrieve nonstring parameter data from the buffer. Use GetParamString to retrieve string parameter data from the buffer.
