make.db.names-MySQLConnection-character-method: Make R/S-Plus identifiers into legal SQL identifiers

In rstats-db/RMySQL: Database Interface and 'MySQL' Driver for R

Make R/S-Plus identifiers into legal SQL identifiers

Description

These methods are straight-forward implementations of the corresponding generic functions.

Usage

## S4 method for signature 'MySQLConnection,character'
make.db.names(
  dbObj,
  snames,
  keywords = .SQL92Keywords,
  unique = TRUE,
  allow.keywords = TRUE,
  ...
)

## S4 method for signature 'MySQLConnection'
SQLKeywords(dbObj, ...)

## S4 method for signature 'MySQLConnection,character'
isSQLKeyword(
  dbObj,
  name,
  keywords = .MySQLKeywords,
  case = c("lower", "upper", "any")[3],
  ...
)

Arguments

dbObj	any MySQL object (e.g., MySQLDriver).
snames	a character vector of R/S-Plus identifiers (symbols) from which we need to make SQL identifiers.
keywords	a character vector with SQL keywords, by default it is .MySQLKeywords define in RMySQL. This may be overriden by users.
unique	logical describing whether the resulting set of SQL names should be unique. Its default is TRUE. Following the SQL 92 standard, uniqueness of SQL identifiers is determined regardless of whether letters are upper or lower case.
allow.keywords	logical describing whether SQL keywords should be allowed in the resulting set of SQL names. Its default is TRUE
...	Unused, needed for compatibility with generic.
name	a character vector of SQL identifiers we want to check against keywords from the DBMS.
case	a character string specifying whether to make the comparison as lower case, upper case, or any of the two. it defaults to any.
