JDBC using REFERENCES
In an application that uses JDBC I am trying to use the following statement
* // Table parameters
var sql = new MyString();
sql.setData("CREATE TABLE IF NOT EXISTS ");
sql.append(this.tableName);
sql.append(" (");
sql.append("index SERIAL NOT NULL, ");
sql.append("id TEXT PRIMARY KEY, ");
sql.append("day TEXT NOT NULL, ");
sql.append("month TEXT NOT NULL, ");
sql.append("year TEXT NOT NULL, ");
sql.append("hour TEXT NOT NULL, ");
sql.append("minute TEXT NOT NULL, ");
sql.append("second TEXT NOT NULL, ");
sql.append("millisecond TEXT NOT NULL, ");
sql.append("am_pm TEXT NOT NULL, ");
sql.append("admin boolean NOT NULL DEFAULT false, ");
sql.append("CONSTRAIN id PRIMARY KEY (id)"); *_<== Error_*
sql.append(");");*
but I get a message saying :
Exception in thread "main" java.sql.SQLException: In
company.contact.createTable()
ERROR: syntax error at or near "("
Position: 315
Does JDBC allow us to do this?
What am I doing wrong?
How to fix this

The word constraint ends with a “T”

Collapse all the append()s after rable e and see if parentheses are balanced.
Show quoted text

This is quite confusing, having the index column be serial but not PK (or
even unique…) while the id column is the PK, which you’ve redundantly
specified.
