Method Detail

isSelect

public static boolean isSelect(String sqlCommand)

We only use the selects that refer to objects in the database that are meaningful for testing purposes, when code access to a sequence for example when getting the next id for a new object in the table, then we don't want to use that select as a target.

Parameters:

sqlCommand -

Returns:

isDelete

public static boolean isDelete(String sqlCommand)

isUpdate

public static boolean isUpdate(String sqlCommand)

isInsert

public static boolean isInsert(String sqlCommand)

isSelectOne

public static boolean isSelectOne(String sqlCommand)

check if the sql is `Select 1` detected by proxyprint as ERROR - FAILED TO COMPUTE HEURISTICS FOR SQL: SELECT 1

getWhere

public static net.sf.jsqlparser.expression.Expression getWhere(net.sf.jsqlparser.statement.Statement parsedStatement)

getFrom

public static net.sf.jsqlparser.statement.select.FromItem getFrom(net.sf.jsqlparser.statement.Statement parsedStatement)

Extracts the "FROM" clause or the primary table involved in a SQL statement. This method supports SELECT, DELETE, and UPDATE SQL statements.

Parameters:

parsedStatement - The parsed SQL statement as a Statement object. This is typically obtained using JSQLParser's `CCJSqlParserUtil.parse`.

Returns:

The FromItem representing the "FROM" clause or the main table for the statement. - For a SELECT statement, returns the main FromItem in the "FROM" clause. - For a DELETE statement, returns the table being deleted from. - For an UPDATE statement, returns the table being updated.

Throws:

IllegalArgumentException - If the provided statement type is not SELECT, DELETE, or UPDATE.

getJoins

public static List<net.sf.jsqlparser.statement.select.Join> getJoins(net.sf.jsqlparser.statement.Statement parsedStatement)

parseSqlCommand

public static net.sf.jsqlparser.statement.Statement parseSqlCommand(String sqlCommand)

This method assumes that the SQL command can be successfully parsed.

Parameters:

sqlCommand - to be parsed

Returns:

the AST root node

canParseSqlStatement

public static boolean canParseSqlStatement(String sqlCommand)

isTable

public static boolean isTable(net.sf.jsqlparser.statement.select.FromItem fromItem)

Checks if the given FromItem is a Table.

Parameters:

fromItem - the FromItem to check

Returns:

true if the FromItem is a Table, false otherwise

getTableName

public static String getTableName(net.sf.jsqlparser.statement.select.FromItem fromItem)

Retrieves the fully qualified name of a table from the provided FromItem.

This method checks if the given fromItem is an instance of Table. If it is, the method extracts and returns the fully qualified name of the table. Otherwise, it throws an IllegalArgumentException.

Parameters:

fromItem - the FromItem instance to extract the table name from.

Returns:

the fully qualified name of the table as a String.

Throws:

IllegalArgumentException - if the provided fromItem is not an instance of Table.

public static boolean isUnion(net.sf.jsqlparser.statement.Statement statement)

Checks if the given Statement is a UNION statement.

Parameters:

statement -

Returns:

getFromAndJoinItems

public static List<net.sf.jsqlparser.statement.select.FromItem> getFromAndJoinItems(net.sf.jsqlparser.statement.select.Select select)

Retrieves the "FROM" and "JOIN" items from a given SQL SELECT statement.

Parameters:

select - the SQL SELECT statement

Returns:

a list of FromItem objects representing the "FROM" and "JOIN" items
