SQLServerF1

ORA-24804: Lob read/write functions called while another OCI LOB read/write streaming is in progress
Cause: Internal error.
Action: Wait for the ongoing LOB streaming call to finish before issuing the next server call, or use OCIBreak() abort the current LOB streaming call.
ORA-24805: LOB type mismatch
Cause: When copying or appending LOB locators, both source and desctination LOB locators should be of the same type.
Action: Pass the same type of LOB locators for copying or appending.

ORA-24806: LOB form mismatch
Cause: When reading from or writing into LOBs, the character set form of the user buffer should be same as that of the LOB.
Action: Make sure that the buffer you are using to read or write has the same form as that of the LOB.
ORA-24807: LOB form mismatch
Cause: When copying or appending LOBs, both source and desctination LOB locators should have the same character set form.
Action: Pass locators of the same character set form for copying or appending LOBs.
ORA-24808: streaming of lob data is not allowed when using lob buffering
Cause: Attempted to stream lob data via the polling mode or a callback when lob buffering was enabled for the input lob locator.
Action: Lob buffering is useful when reading/writing small amounts of lob data so streaming should not be necessary. Rewrite the OCILobRead/OCILobWrite call so that it does not use streaming. If streaming of data is required, lob buffering should not be used. In this case, flush buffers associated with the input lob locator as necessary, disable buffering on the input lob locator and reissue the OCILobRead/OCILobWrite call.

ORA-24809: amount specified will not fit in the lob buffers
Cause: LOB buffering is enabled for the input lob locator so buffering will be used. However, the amount of lob data to read or write is larger than what the lob buffers can hold.
Action: Either disable buffering on the input lob locator and reissue the command or pass a smaller amount.
ORA-24810: attempting to write more data than indicated
Cause: While writing into a LOB, more data was supplied than indicated.
Action: If data is written in pieces, then make sure that you do not provide more data in the pieces (cumulatively), than you indicated.
ORA-24811: less data provided for writing than indicated
Cause: While writing into a LOB, less data was provided than indicated.
Action: If writing data in single pieces, then make sure that the buffer length specified is big enough to accommodate tha data being provided. If data is written in pieces, then make sure that all the data has been provided before specifying OCI_LAST_PIECE.
ORA-24812: character set conversion to or from UCS2 failed
Cause: If the database character set is varying-width, the CLOB/NCLOB value is implicitly converted to or from UCS2. This implicit conversion failed.
Action: Contact Oracle Worldwide Support.
