Value length exceeds the parameter size

[srjraja]

Hi,

Am using DevArt for Oracle version 670Pro, getting below exception while performing execute non query operation,

Exception :: An error occurred while executing the command definition. See the inner exception for details.
InnerException :: Devart.Data.Oracle.OracleException (0x80004005): Value length exceeds the parameter size

the snippet given below is an auto generated using devart entity model template.

EntityParameter P_ACTION_STATUS_CODEParameter = new EntityParameter("P_ACTION_STATUS_CODE", System.Data.DbType.String);
if (P_ACTION_STATUS_CODE != null)
P_ACTION_STATUS_CODEParameter.Value = P_ACTION_STATUS_CODE;

My problem is while inserting a string of length 32000 throwing the above exception. But it works normally with string of minimal length. Please provide solution to this issue ASAP.

Hi,

Found a way to close this issue, have used EntityParameter TName = new EntityParameter("Name", System.Data.DbType.AnsiString, 80000);

AnsiString accepts 8k chars by default, and you have an option of resetting the size. Also, please check the length of the string you are going to insert, i was in need of 32k chars to be pushed, hence declared almost double the size.

Hope this helps someone,

Cheers,
Raj

The size of the VARCHAR2 parameter in Oracle can be up to 32KB (not more). You should use the CLOB data type for bigger data. Please use the dbMonitor tool that performs per-component tracing of database events such as commit, rollback, SQL statement execute etc to find out the data type of the parameter which is sent to server:
