Enter CQL using the following format:

• CQL uses a free format. Operands are specified in the order described in each CQL format. For the CQL formats, see 4. CQL Reference.
• CQL statements are separated using a semicolon (;).
  A statement may span multiple lines, but multiple statements cannot be entered on a single line.
  Correct and incorrect coding examples follow:
  

  Correct coding example

  REGISTER STREAM s1(id INT,name VARCHAR(10)); REGISTER QUERY q1 SELECT s1.name FROM s1[ROWS 10];

  Incorrect coding example

  REGISTER STREAM s1(id INT); REGISTER QUERY q1 SELECT * FROM s1[ROWS 10];

  An error occurs because two REGISTER statements are entered on a single line.

• To enter comments, use two forward slashes (//). After the two forward slashes are entered, the rest of the text on the line is treated as a comment. You cannot insert comments in the middle of a statement.
  Correct and incorrect coding examples follow:
  

  Correct coding example

  // comments REGISTER STREAM s1(id INT,name VARCHAR(10)); // comment

  Incorrect coding example

  REGISTER QUERY q1 // comment SELECT s1.name FROM s1[ROWS 10];

  An error occurs because a comment is inserted in the middle of the REGISTER QUERY statement.

  If you need to enter two forward slashes (//) in the middle of a character string for a purpose other than entering comments, make sure the forward slashes do not occur at the beginning of a line. Correct and incorrect coding examples follow:
  

  Correct coding example

  REGISTER QUERY q1 SELECT * FROM s1[NOW] WHERE s1.c1='ab//cd';

  Incorrect coding example

  REGISTER QUERY q1 SELECT * FROM s1[NOW] WHERE s1.c1='ab //cd';

  An error occurs because a line begins with two forward slashes (the line is treated as a comment line).
