This is the MySQL code I have so far: CREATE DATABASE bankbase; USE bankbase; CREATE TABLE clienttable( ClientID SMALLINT(15) NOT NULL DEFAULT 0, ClientFirstName VARCHAR(30) NOT NULL DEFAULT "first name", ClientLastName VARCHAR(30) NOT NULL DEFAULT "last name", ClientPhone CHAR(10) NOT NULL, ClientEmail TINYTEXT(30) NULL, ClientAddress TINYTEXT(128) NOT NULL, PRIMARYKEY(ClientID) ); CREATE TABLE branchtable( BranchID SMALLINT(15) NOT NULL DEFAULT 0, BranchCity TINYTEXT(30) NOT NULL DEFAULT city, BranchManagerFName VARCHAR(30) NULL DEFAULT "Branch Manager's First Name", BranchManagerLName

I'm trying to create this function: CREATE FUNCTION remove_non_alphanum (prm_strInput varchar(3000)) RETURNS VARCHAR(3000) DETERMINISTIC BEGIN DECLARE i INT DEFAULT 1; DECLARE v_char VARCHAR(1); DECLARE v_parseStr VARCHAR(3000) DEFAULT ''; WHILE (i <= LENGTH(prm_strInput) ) DO SET v_char = SUBSTR(prm_strInput,i,1); IF v_char REGEXP '^[A-Za-z0-9]$' THEN SET v_parseStr = CONCAT(v_parseStr,v_char); END IF; SET i = i + 1; END WHILE; RETURN trim(v_parseStr); END But MySQL says: 13:52:45 [CREATE - 0 row(s), 0.000 secs] [Error Code: 1064, SQL State: 42000] You have an error in your SQL syntax; check

I created a Spatial table Points using SQL Editor in MySQL workbench. To fill this table, the following is the code I am using. CREATE PROCEDURE fill_points( IN size INT(10) ) BEGIN DECLARE i DOUBLE(10,1) DEFAULT size; DECLARE lon FLOAT(7,4); DECLARE lat FLOAT(6,4); DECLARE position VARCHAR(100); -- Deleting all. DELETE FROM Points; WHILE i > 0 DO SET lon = RAND() * 360 - 180; SET lat = RAND() * 180 - 90; SET position = CONCAT( 'POINT(', lon, ' ', lat, ')' ); INSERT INTO Points(name, location) VALUES ( CONCAT('name_', i), GeomFromText(position) ); SET i = i - 1; END WHILE; END when I executed

Why I try to do an order by query, I always get an error telling me to check the syntax by the ORDER BY 'order' DESC.... Here's my query: SELECT * FROM posts ORDER BY order DESC; What am I doing wrong?? order is a reserved word in SQL; case does not matter. It must be quoted when used as an identifier . From the MySQL Reserved Words documentation: Certain words such as SELECT, DELETE, or BIGINT [or ORDER] are reserved and require special treatment for use as identifiers such as table and column names. Traditional MySQL quotes: SELECT * FROM posts ORDER BY `order` DESC; Proper (ANSI) SQL quotes

I am getting the Exception with the signature No operations allowed after statement closed. inside my Java code where I am trying to insert values into the database. The error signature says that my Statement object gets closed and I am trying to use it again in my code , but what I am struggling to understand is why is this happening as I am not closing any connections anywhere in my code. Here is the Java code. public class DataBaseAccessUtils { private static String jdbcUrl = AppConfig.findMap("BXRequestTracker").get("jdbcUrl").toString(); private static Connection connection = null;
