Show Table(s) From Terminal Command Line

All Tables in Database

SELECT table_name AS "Tables",  round(((data_length + index_length) / 1024 / 1024), 2) "Size in MB"  FROM information_schema.TABLES  WHERE table_schema = "io85" ORDER BY (data_length + index_length) DESC;

Single Table

SELECT table_name AS "Table", 
round(((data_length + index_length) / 1024 / 1024), 2) "Size in MB" 
FROM information_schema.TABLES 
WHERE table_schema = "$DB_NAME"
 AND table_name = "$TABLE_NAME";

Backup All Databases

mysqldump -n --user=XXXX --password=XXXX --all-databases | gzip -c > server.sql.gz

Dump Data and Structure

mysqldump -u root -p --skip-add-drop-table --replace --skip-extended-insert --lock-tables io85_com | sed 's/CREATE TABLE/CREATE TABLE IF NOT EXISTS/g' > io85_com_full.sql

Dump Data Only

mysqldump -u root -p --no-create-info --skip-add-drop-table --replace --skip-extended-insert --lock-tables io85_com > data_dump.sql

Dump Structure Only

mysqldump -u root -p --no-data --skip-add-drop-table --replace --skip-extended-insert --lock-tables io85_com | sed 's/CREATE TABLE/CREATE TABLE IF NOT EXISTS/g' > schema_dump.sql

Select DB for Import

mysql -u root -p --one-database db_to_restore < fulldump.sql

Extract Database from Dump File

sed -n '/^-- Current Database: `test`/,/^-- Current Database: `/p' fulldump.sql > test.sql

Basic my.cnf

[mysqld]
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
skip_external_locking
#skip-networking
skip-name-resolve
default-storage-engine=innodb

Ucwords for Mysql

DROP FUNCTION IF EXISTS proper;
SET GLOBAL  log_bin_trust_function_creators=TRUE;
DELIMITER |
CREATE FUNCTION proper( str VARCHAR(128) )
RETURNS VARCHAR(128)
BEGIN
  DECLARE c CHAR(1);
  DECLARE s VARCHAR(128);
  DECLARE i INT DEFAULT 1;
  DECLARE bool INT DEFAULT 1;
  DECLARE punct CHAR(17) DEFAULT ' ()[]{},.-_!@;:?/';
  SET s = LCASE( str );
  WHILE i < LENGTH( str ) DO 
    BEGIN
      SET c = SUBSTRING( s, i, 1 );
      IF LOCATE( c, punct ) > 0 THEN
        SET bool = 1;
      ELSEIF bool=1 THEN

          IF c >= 'a' AND c <= 'z' THEN 
            BEGIN
              SET s = CONCAT(LEFT(s,i-1),UCASE(c),SUBSTRING(s,i+1));
              SET bool = 0;
            END;
          ELSEIF c >= '0' AND c <= '9' THEN
            SET bool = 0;
          END IF;
        END;
      END IF;
      SET i = i+1;
    END;
  END WHILE;
  RETURN s;
END;
