Question

while executing the following query, i get an error that there’s an error in the syntax near line 9. since i’m using mysql workbench, i can’t really figure out what could be wrong:

CREATE  TABLE IF NOT EXISTS `proquotes`.`thquotes` (

  `idQuotes` INT NOT NULL AUTO_INCREMENT ,

  `vAuthorID` VARCHAR(8) CHARACTER SET 'utf8' NOT NULL ,

  `vAuthor` VARCHAR(45) CHARACTER SET 'utf8' NOT NULL ,

  `cQuotes` MEDIUMTEXT CHARACTER SET 'utf8' NOT NULL ,

  `cArabic` MEDIUMTEXT CHARACTER SET 'utf8' NOT NULL ,

  `vReference` VARCHAR(100) CHARACTER SET 'utf8' NOT NULL ,

  PRIMARY KEY (`idQuotes`) ,

  INDEX `vAuthorID` () ,

  CONSTRAINT `vAuthorID`

    FOREIGN KEY ()

    REFERENCES `proquotes`.`author_info` ()

    ON DELETE NO ACTION

    ON UPDATE NO ACTION)

DEFAULT CHARACTER SET = utf8;

table author_info:

CREATE  TABLE IF NOT EXISTS `proquotes`.`author_info` (  

`vAuthorID` INT NOT NULL ,  `vAuthor` VARCHAR(45) CHARACTER 

SET 'utf8' NOT NULL ,  `nQuotes` INT NOT NULL ,  PRIMARY KEY 

(`vAuthorID`) ,  UNIQUE INDEX `vAuthorID_UNIQUE` (`vAuthorID` 

ASC) )DEFAULT CHARACTER SET = utf8;

Answer 1

The syntax error appears to be the empty parenthesis at: INDEX vAuthorID (), FOREIGN KEY () and REFERENCES proquotes.author_info (). Those parenthesis should reference one or more table attributes.

For example:

INDEX `vAuthorID` (`vAuthorID`) ,
CONSTRAINT `vAuthorID`
   FOREIGN KEY (`vAuthorID`)
   REFERENCES `proquotes`.`author_info` (`vAuthorID`)

The last parenthesis for the REFERENCES clause should reference an attribute in author_info, and not from thquotes. Therefore you may need to change vAuthorID accordingly.
