Why am I getting SQLSyntaxErrorException - encountered ""?
This method keeps throwing the exception in the title, and I cannot find a reason, I have created other tables through the co开发者_高级运维nnection and all the referenced tables have been created. I'm using embedded JavaDB.
private void createEvidenceTable() throws SQLException
{
Statement evidenceTable = CONNECTION.createStatement();
evidenceTable.execute("CREATE TABLE evidence("+
"evidence_id INTEGER NOT NULL PRIMARY KEY,"+
"date_added VARCHAR(6) NOT NULL,"+
"evidence_dated VARCHAR(6) NOT NULL,"+
"evidence_file varchar(20),"+
"evidence_text VARCHAR(10),"+
"source_location_id INTEGER,"+
"source_person_id INTEGER,"+
"evidence_type VARCHAR(20),"+
"CONSTRAINT evidence__location_source FOREIGN KEY(source_location_id) REFERENCES location_source,"+
"CONSTRAINT evidence_person_source FOREIGN KEY(source_person_id) REFERENCES person_source,"+
"CONSTARINT evidence_evidence_type FOREIGN KEY(evidence_type) REFERENCES evidence_types)");
}
One definite problem is that the third constraint clause is misspelled (CONSTARINT
iso CONSTRAINT
)
This worked in MySQL client:
CREATE TABLE evidence
(
evidence_id INTEGER NOT NULL,
date_added VARCHAR(6) NOT NULL,
evidence_dated VARCHAR(6) NOT NULL,
evidence_file varchar(20),
evidence_text VARCHAR(10),
source_location_id INTEGER,
source_person_id INTEGER,
evidence_type VARCHAR(20),
PRIMARY KEY(evidence_id),
FOREIGN KEY(source_location_id) REFERENCES location_source(source_location_id),
FOREIGN KEY(source_person_id) REFERENCES person_source(source_person_id),
FOREIGN KEY(evidence_type) REFERENCES evidence_types(evidence_type)
);
Why would you use VARCHAR(6) instead of DATE? Makes little sense to me.
