Why am I getting \'cannot issue data manipulation statements with executeQuery()\'?

Unable to Execute Data Manipulation Queries with executeQuery()

When encountering the error "cannot issue data manipulation statements with executeQuery()", it indicates that an invalid method is being used for modifying data. To resolve this issue, it is crucial to understand the distinction between executeUpdate() and executeQuery().

The executeQuery() method is designed for executing SELECT statements that retrieve data from a database and return a ResultSet object containing the results. It is not suitable for making changes to the database, such as inserting, updating, or deleting data.

For data manipulation operations, such as the provided queries (query1 and query2), it is necessary to utilize the executeUpdate() method. This method is specifically предназначен to execute INSERT, UPDATE, DELETE, or other SQL statements that do not return any results. When used properly, executeUpdate() modifies the data in the database according to the provided query.

Therefore, to correct the issue, replace the executeQuery() calls with executeUpdate() calls for the data manipulation queries. This adjustment ensures that the queries are executed in the appropriate manner, allowing for successful data manipulation operations.
