complexity of the embedded SQL statements (for example, the number of bind and define variables). There is no absolute limit to the number of lines allowed, but the following aspects of the source file are contributing factors to the file-size constraint: Some of the variables used internally limit the size of the generated file. The Pro*FORTRAN Precompiler cannot process arbitrarily long source files. The precompiler translates all EXEC SQL statements into calls to the runtime library SQLLIB. Embedded SQL syntax is described in the Oracle7 Server SQL Reference. To use a SQL statement in your host program, precede the SQL statement with the EXEC SQL clause. SQL also uses apostrophes to delimit string literals, as in * Retrieve employee data.īut SQL uses quotation marks to delimit identifiers containing special or lowercase characters, as in * Create table.ĮXEC SQL CREATE TABLE "Emp2" (EMPNO NUMBER(4). FORTRAN uses apostrophes to delimit string literals, as in * Display employee name. Though FORTRAN does not require blanks to delimit keywords, you must use blanks to delimit keywords in SQL statements. Check your FORTRAN compiler user's guide. Most FORTRAN implementations allow up to 19 continuation lines. An example follows: * Execute dynamic SQL statement.ĮXEC SQL EXECUTE IMMEDIATE 'UPDATE EMP SET COMM = 500 WHERE #Editpad pro remember open files on shutdown code#
On the next line, code a continuation character and the rest of the literal. To continue a string literal from one line to the next, code the literal through column 72. In this manual, digits are used as continuation characters, as the following example shows: * Retrieve employee data. To code a continuation line, place a non-zero, non-blank character in column 6. You can continue SQL statements from one line to the next, according to the rules of FORTRAN.
Blank lines are treated as comments, but are not allowed within a continued statement. The following example shows all three styles of comments: EXEC SQL SELECT ENAME, SALĬ Assign column values to host variables.ġ INTO :ENAM, :ESAL - output host variables ) in SQL statements at the end of a line, and you can place C-style comments (/*. You can also place ANSI SQL-style comments (. FORTRAN comment lines start with the letter C or an asterisk (*) in column 1. You can place FORTRAN comment lines within SQL statements. No more than one statement can appear on a single line. In this manual, the program fragments and sample programs are in ANSI format (FORMAT=ANSI). On some systems, terminal format is supported that is, entry is not restricted to certain columns.
Columns 2 through 5 can contain an optional statement label. Column 1 can indicate a comment line or can be part of an optional statement label. The other columns are used for the following purposes: You must code EXEC SQL and EXEC ORACLE statements in columns 7 through 72 (columns 73 through 80 are ignored). If your compiler is case-sensitive, you must declare and reference variables in the same uppercase/lowercase format. The Pro*FORTRAN Precompiler is not case-sensitive however, some compilers are. Though the standard FORTRAN character set excludes lowercase alpha characters, many compilers allow them in identifiers, comments, and quoted literals. Topics are arranged alphabetically for quick reference. This section deals with embedded SQL syntax, coding conventions, and FORTRAN-specific features and restrictions.
