How to use a tablename variable for a java prepared statement insert
dynamic, java, prepared-statement, sql, variables
Solution
You can't. You need to contruct the sql with string concatenation/placeholder with String.format. prepared statement is for the column values not for table name.
Problem
I am using a java PreparedStatment object to construct a series of batched INSERT queries. The query statement is of the format... ``` String strQuery = "INSERT INTO ? (col1, col2, col3, col4, col5) VALUES (?,?,?,?,?,?);"; ``` ...so both field values and the tablename are variables (ie. I have multiple tables with the same column format of which each insert will be directed to a different one). I can get the executes to work if I remove the "?" tablename variable and hard code but each prepared statement will be inserted into a different table so needs to remain a variable I populate immediately prior to executing the batch query using... ``` stmt.setString(1, "tableName1"); ``` How can I let this be a dynamic variable please?
