How to convert SQL to line converter online?

In the context of SQL, You can convert an SQL query into a line-by-line format by using an online “SQL to line converter” by using these steps:-

Select an SQL query

You can start by identifying the SQL query which you need to convert. For example, let's suppose you have the following complex queries:-

SELECT e.employee_id, e.first_name, e.last_name, d.department_name

FROM employees e

JOIN departments d ON e.department_id = d.department_id

WHERE e.hire_date > ‘2020-01-01’

ORDER BY e.last_name;

Accessing the SQL to line converter tool

You can try to navigate to the online SQL to-line tool. This tool has an interactive where you can paste your SQL query.

Input the SQL query

You can paste the SQL query into the provided text area. You should try to ensure that the query is syntactically correct and formatted properly.

Configure conversion setting

Some of the converters may allow you to configure settings, such as choosing whether to include line numbers, handling the line break, or even maintaining comments.

Implement the conversion

You can click on the convert button or even the equivalent option to transform your SQL query into a line-by-line format. These tools would help you break down the query, placing each SQL statement or even clause on a separate line.

Reviewing the output

You can examine the output which is provided by the tool. It should look like something like this:-

SELECT e.employee_id,

       e.first_name,

       e.last_name,

       d.department_name

FROM employees e

JOIN departments d ON e.department_id = d.department_id

WHERE e.hire_date > ‘2020-01-01’

ORDER BY e.last_name;

Here is the java based example given below of how you can convert an SQL query Into a line-by-line format programmatically by using the java:-

Import java.io.BufferedReader;

Import java.io.BufferedWriter;

Import java.io.FileReader;

Import java.io.FileWriter;

Import java.io.IOException;

Public class SQLToLineConverter {

    /**

     * Reads an SQL query from a file, formats it line-by-line, and writes the output to another file.

     *

     * @param inputFilePath  Path to the file containing the original SQL query.

     * @param outputFilePath Path to the file where the formatted SQL query will be written.

     * @throws IOException if an I/O error occurs.

     */

    Public static void convertSQLToLine(String inputFilePath, String outputFilePath) throws IOException {

        // Reading the SQL query from a file

        StringBuilder sqlQuery = new StringBuilder();

        Try (BufferedReader reader = new BufferedReader(new FileReader(inputFilePath))) {

            String line;

            While ((line = reader.readLine()) != null) {

                sqlQuery.append(line).append(“ “);

            }

        }

        // Processing and formatting the SQL query

        String formattedSQL = formatSQLQuery(sqlQuery.toString());

        // Writing the formatted SQL query to another file

        Try (BufferedWriter writer = new BufferedWriter(new FileWriter(outputFilePath))) {

            Writer.write(formattedSQL);

        }

    }

    /**

     * Formats an SQL query by breaking it into lines.

     *

     * @param sqlQuery The original SQL query.

     * @return The formatted SQL query.

     */

    Private static String formatSQLQuery(String sqlQuery) {

        String formattedQuery = sqlQuery

                .replaceAll(“(?i)\s*(SELECT|FROM|WHERE|JOIN|ON|ORDER BY|GROUP BY|HAVING|AND|OR|INNER JOIN|LEFT JOIN|RIGHT JOIN)\s*”, “

                .trim();

        // Further formatting to ensure neat indentation

        String[] lines = formattedQuery.split(\n);

        StringBuilder formattedSQL = new StringBuilder();

        String indent = “”;

        For (String line : lines) {

            if (line.trim().matches(“(?i).*\b(SELECT|JOIN|WHERE|ORDER BY|GROUP BY)\b.*”)) {

            }

        }

        Return formattedSQL.toString();

    }

    Public static void main(String[] args) {

        If (args.length != 2) {

            System.out.println(“Usage: java SQLToLineConverter  ”);

            Return;

        }

        String inputFilePath = args[0];

        String outputFilePath = args[1];

        Try {

            convertSQLToLine(inputFilePath, outputFilePath);

            System.out.println(“SQL query formatted successfully. Check the output file: “ + outputFilePath);

        } catch (IOException e) {

            System.err.println(“Error while processing the SQL query: “ + e.getMessage());
