Download the latest mysql connector J for you mysql server from their website. 

[https://dev.mysql.com/downloads/connector/j/5.1.html]
\\
Direct link: [https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.47.zip]
\\
Alternatively, can browse the Maven repository for the appropriate JDBC drive matching your SQL server version, if not using the latest build of it
[https://mvnrepository.com/artifact/mysql/mysql-connector-java]
\\
I suggest placing the mysql-connector-java-5.0.8-bin.jar file from this in the plugins/lib folder of CrushFTP and giving it the name "mysql.jar".

Then go to Preferences, stats config and set the following items:
\\
[{Image src='sql_stats1.jpg' width='..' height='..' align='left|center|right' style='..' class='..' }]
\\
{{{
stats_db_url: jdbc:mysql://127.0.0.1:3306/crushftp_stats
stats_db_driver: com.mysql.jdbc.Driver
stats_db_user: root
stats_db_driver_file: plugins/lib/mysql.jar
}}}\\
\\
Use MySQL Workbench and make a new DB with the name "crushftp_stats" (or adjust the URL above to reference the name you choose.)  Below is the schema to put in it:\\
\\
{{{
CREATE TABLE META_INFO(RID DOUBLE NOT NULL PRIMARY KEY,SESSION_RID DOUBLE NOT NULL,TRANSFER_RID DOUBLE NOT NULL,ITEM_KEY VARCHAR(100) DEFAULT NULL,ITEM_VALUE VARCHAR(2000) DEFAULT NULL);

CREATE TABLE SESSIONS(RID DOUBLE NOT NULL PRIMARY KEY,SESSION VARCHAR(100) DEFAULT NULL,SERVER_GROUP VARCHAR(50) DEFAULT NULL,USER_NAME VARCHAR(100) DEFAULT NULL,START_TIME DATETIME DEFAULT NULL,END_TIME DATETIME DEFAULT NULL,SUCCESS_LOGIN VARCHAR(10) DEFAULT NULL,IP VARCHAR(50) DEFAULT NULL);

CREATE TABLE TRANSFERS(RID DOUBLE NOT NULL PRIMARY KEY,SESSION_RID DOUBLE NOT NULL,START_TIME DATETIME DEFAULT NULL,DIRECTION VARCHAR(8) DEFAULT NULL,PATH VARCHAR(255) DEFAULT NULL,FILE_NAME VARCHAR(2000) DEFAULT NULL,URL VARCHAR(2000) DEFAULT NULL,SPEED INTEGER DEFAULT NULL,TRANSFER_SIZE DOUBLE DEFAULT NULL,IGNORE_SIZE VARCHAR(1) DEFAULT NULL);

ALTER TABLE `TRANSFERS` ADD INDEX  (`SESSION_RID`,`TRANSFER_SIZE`,`DIRECTION`,`IGNORE_SIZE`,`START_TIME`);

}}}\\
\\
That is it.  Now the statistics data should be going to the MySQL tables, and reports will automatically run against those tables too.\\
\\
!! Setup Auto increment primary keys
\\
1. On prefs.XML (find it at CrushFTP install folder) change the tag value "__stat_auto_increment__" to __true__.\\
\\
2. Change the RID column (on META_INFO, SESSIONS and TRANSFERS table) to be auto incremented and data type from DOUBLE to BIGINT.\\
\\
{{{
ALTER TABLE `META_INFO` CHANGE COLUMN `RID` `RID` BIGINT(20) NOT NULL AUTO_INCREMENT;

ALTER TABLE `SESSIONS` CHANGE COLUMN `RID` `RID` BIGINT(20) NOT NULL AUTO_INCREMENT;

ALTER TABLE `TRANSFERS` CHANGE COLUMN `RID` `RID` BIGINT(20) NOT NULL AUTO_INCREMENT;
}}}\\
\\
3. Adjust insert queries. Remove the __RID__ value from the query.\\

Change stats_insert_meta_info from:\\ 
{{{
INSERT INTO META_INFO (RID, SESSION_RID, TRANSFER_RID, ITEM_KEY, ITEM_VALUE) VALUES (?,?,?,?,?)
}}}\\
to:\\
__{{{
INSERT INTO META_INFO (SESSION_RID, TRANSFER_RID, ITEM_KEY, ITEM_VALUE) VALUES (?,?,?,?)
}}}__
