1 Quick-and-dirty

2

3  Commands end in a semi-colon ◦ If you forget, another prompt line shows up  Either continue the command or…  End it with a semi-colon ◦ Just like “DOS”…  No error message, and another command prompt indicates that the command worked (assumption)

4

5  Just because it exists doesn’t mean that you’re using it ◦ Issue the “USE DATABASE ” command ◦ Empty database  No tables exist in it

6  Use the CREATE TABLE command ◦ For the fields (columns) consider:  Names  Data type  Unique value in that table?  Index value?  Primary key?  Auto Increment?  Any default value?  Null or not null?

7  Note the continuation line for the command ◦ Field (column) definitions are separated by commas  Each field is described  SHOW TABLES command is issued to verify the table exists

8  Use the “DESCRIBE” command

9  Use an “INSERT INTO” SQL command  Load records from another source ◦ From another table using SQL ◦ From a sequential file using the “LOAD” command

10  parts.txt ◦ Text file ◦ Semi-colon separated values ◦ Lines end on “newline” character

11  Command line interface (MySQL shell) indicated that 3 records were affected  Use a “select” query to show the records
