How to resolve errors when using “select into” in Oracl…

There are various reasons and solutions for errors that may occur when using the SELECT INTO statement in Oracle.

1. Error ORA-00905: missing keyword
   This error commonly occurs due to incorrect syntax in the SELECT INTO statement. Make sure to use the INTO keyword after the SELECT statement and store the result in the correct variable.
2. Error ORA-01403: no data found
   This error typically occurs when a SELECT INTO statement does not return any data. Ensure that the query returns data, and check the results of the query before running the SELECT INTO statement.
3. ORA-06502 error: numerical or runtime error
   This error typically occurs when a SELECT INTO statement attempts to assign the result to a variable of an incompatible type. Make sure the target variable is compatible with the data type of the query result.
4. ORA-01008 error: invalid connection identifier
   This error typically occurs when a SELECT INTO statement is trying to execute on an invalid database connection. Make sure you are connected to the correct database and that the connection is open.
5. Error ORA-00933: SQL command not properly ended
   This error usually occurs due to incorrect syntax in the SELECT INTO statement. Make sure the statement is properly ended and add a semicolon at the end of the statement.
