-  TABLE < tablename | "​tablename"​ > 
- 
-  COLUMN column-name DATATYPE datatype-spec ​ 
-      [PROXIMITY “options”] 
-      {AS "​$retrieve_file(FILENAME)"​ 
- 
- 
-<​code>​ 
- where the “options” are: 
-  
- SPACE=proximity_spec 
-NEAR=proximity_spec 
- BEFORE=proximity_spec 
- PHRASE=proximity_spec 
-  
- and where “proximity_spec” is: 
- 
- NEAR(n) – means insure that word1 is within n words before or after word2. 
- BEFORE(n) – means insure that word1 is within n words before word2 
- PHRASE ​ - means insure that word1 immediately before word 2, and treat as a phrase rather than separate words. 
- 
-The default behavior is as follows: 
- 
- SPACE=NEAR(999) 
-NEAR=NEAR(10) 
- BEFORE=BEFORE(10) 
- PHRASE=PHRASE ​ 
-</​code>​ 
-One other change to the options in the clause is the removal of AUTOENABLE and NOAUTOENABLE. ​ The AUTOENABLE option makes sense for things like SYNONYMS, but it doesn’t make sense for PROXIMITY since proximity is always in effect.  ​
