如何使用 Oracle 和 JDBC 获取 SQL 语句中的错误行号？

Question

In sql developer if we type wrong query, eg delete from notable

it will show us exact line number and column

Error starting at line : 1 in command -
delete from notable
Error at Command Line : 1 Column : 13
Error report -
SQL Error: ORA-00942: table or view does not exist
00942. 00000 -  "table or view does not exist"
*Cause:    
*Action:

but if I do it in java code I got only

java.sql.SQLException: ORA-00942: table or view does not exist

at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112) ~[ojdbc14-10.2.0.3.0.jar:Oracle JDBC Driver version - "10.2.0.3.0"]

How can I obtain information about line and column? is it possible via JDBC?

Answer 1

I'm not aware of any third party library, which will help you to achieve this. But, as far as I know about SQLException , you can't .

And BTW, You are getting above error, because you haven't created table/view, which you were trying to access.

Answer 2

SQLException.getCause() gives you the position of the character at which the exception originated:

    select * from blahblahblah

    Error : 942, Position : 14, Sql = select * from blahblahblah, OriginalSql = select * from blahblahblah, Error Msg = ORA-00942: table or view does not exist

So you could parse the cause and get the character index, then compute the line number and the column number.

This goes for JDBC version 12.2.0.1 and Oracle 12c, not sure about other versions.

Answer 3

From the Command Line, we can execute multiple SQL queries at a time. So, while execution if we get any error, command line processor gives "Line" and "Column" to help the user to know about the faulty line. Anyways, Its a utility provided by Database.

However, In JDBC you can either execute a single query or execute the batch of statements. In both cases you won't get any Line Number and Column Number because its not useful in any sense. Though you can get the reason of error and code, based on your JDBC driver.

Answer 4

I solved this in Python by using the offset (# chars) to determine what line the error happened on. This can be done by looping through the original sql statement and counting the lines while also keeping track of the number of characters seen so far.
