问题 I'm building a SQL statement that contains data and I'm wondering if I would break some maximum statement length in Oracle 10g. The statement would be about 3 200 000 bytes, cannot be split and has to be parsable in its entirety. Before I'm investing too much time this way, I was wondering if I would be limited by the size of this statement. I am using SQL developer but I think that if the server can do it, so can SQL developer. 回答1: There is no fixed number. See "Logical Database Limits":

问题 In an Oracle Database, what are the differences between the following: user() sys_context('USERENV', 'CURRENT_USER') sys_context('USERENV', 'SESSION_USER') Are these also possible related values to whatever 'the current user' is? sys_context('USERENV', 'CURRENT_SCHEMA') sys_context('USERENV', 'AUTHENTICATED_IDENTITY') I am specifically interested in which ones can change, what can change them, which ones can not change value, which ones have different values based on connection type, and

问题 Given this example (DUP_VAL_ON_INDEX Exception), is it possible to capture the values that violated the constraint so they may be logged?

问题 I have the following SQL statement. select emp_no,dob,dept_no from v_depts where catsearch (emp_no,'abc',NULL) > 0 or catsearch (dept_no,'abc',NULL) > 0 where v_depts is a view. Now I would like to add one or more tables as join so that I can do text search on columns e.g. employee_details contains employee information and I can join with emp_no I have created index on employee_details table for emp_name column, however I am not able to join with v_depts to search because I modify my sql

问题 I need to get NHibernate 2.1 to talk to an oracle database. I am being required to use the Oracle 10g client. I get the following error when trying to build my session factory: Unable to cast object of type 'Oracle.DataAccess.Client.OracleConnection' to type 'System.Data.Common.DbConnection'.
