prepared-statement

Trying to parameterize my SQL queries (using libpq function PQexecParams ), I was stuck on a syntax error: SELECT date $1 The error is: ERROR: syntax error at or near "$1" Prepared statements The explanation for this can be found in the chapter Constants of Other Types of the manual : The :: , CAST() , and function-call syntaxes can also be used to specify run-time type conversions of arbitrary expressions, as discussed in Section 4.2.9 . To avoid syntactic ambiguity, the type 'string' syntax can only be used to specify the type of a simple literal constant. Another restriction on the type

I originally had an SQL statement, this: SELECT *, COUNT(friend_one) AS pending_count , COUNT(friend_two) AS requests_sent FROM friends WHERE friend_one OR friend_two = ? AND status = ? In which I assigned my parameters like : $pending_friend_count_stmt->execute(array($user_id, $status_one)); However, the query was not getting the results I wanted. Someone showed me a different way of doing it, but it has the variable $user_id in it multiple times, so I do not know how to adjust the code to be able to use a parameter. You can see the new query here: http://rextester.com/KSM73595 Am I able to

This question already has an answer here: java.sql.SQLException Parameter index out of range (1 > number of parameters, which is 0) [closed] 2 answers I am facing java.sql.SQLException: Parameter index out of range (3 > number of parameters, which is 2). while updating one or two columns of 'reset_info' table which has five columns (id, mobile_tower_id, reset_value, date_time, clientip).

Using Statment, resultSet.getObject returns query plan as xml Connection conn = getConnection(); String query = " SET SHOWPLAN_XML on "; Statement st = conn.createStatement(); boolean execute=st.execute(query); log.info("execute status {} " , execute); query = " SELECT ATMPROFILES.TERMID as COLUMNID, ATMPROFILES.TERMID as COLUMNNAME FROM ATMPROFILES (NOLOCK) " + " WHERE Authprocessname = 'ATMST' " + "ORDER BY ATMPROFILES.TERMID "; ResultSet rs = st.executeQuery(query); while(rs.next()) { Object object = rs.getObject(1); log.info("Query Plan {} ", object); } But If I execute the same through

I am trying to use the preparedStatement Batch but I am having a problem. The following code does not give me errors, but it inserts in the table only last key of the map and I do not know why. It will be surely a very stupid error, but this is the first time I use the addBatch() method.. Class.forName("com.mysql.jdbc.Driver"); this.connect = DriverManager.getConnection("jdbc:mysql://localhost/" + this.database + "?user=" + this.user + "&password=" + this.password); String s; for (String key : this.map.keySet()) { s = ("insert into " + this.database + ".user (nickname) values (?)"); this

I'm trying to create a MySQL Before Insert trigger with the following code which would do what I want it to do if I could find a way to execute the prepared statement generated by the trigger. Are the any alternative ways to execute prepared statements from within triggers? Thanks BEGIN SET @CrntRcrd = (SELECT AUTO_INCREMENT FROM information_schema.TABLES WHERE TABLE_SCHEMA=DATABASE() AND TABLE_NAME='core_Test'); SET @PrevRcrd = @CrntRcrd-1; IF (NEW.ID IS NULL) THEN SET NEW.ID = @CrntRcrd; END IF; SET @PrevHash = (SELECT Hash FROM core_Test WHERE Record=@PrevRcrd); SET @ClmNms = (SELECT CONCAT

Here's the issue. I have a prepared statement, like this: $select_something = $db->stmt_init(); $select_something->prepare (" SELECT whatever FROM table "); $select_something->execute(); $select_something->bind_result($whatever); When alone - it works. When I add another one after it's execution it also works. But when I try to just first prepare them both: $select_something = $db->stmt_init(); $select_something->prepare (" SELECT whatever FROM table "); and execute them later on: $select_something->execute(); $select_something->bind_result($whatever); the first statement gets executed, and
