Storing values in variable
Hi All,

Here is the description of the problem.

I am scripting for database access using k-shell on solaris box
dbaccess <databasename> - << EOF 2>/dev/null | awk 'BEGIN {FS=" "}\
{printf "%s", $1}' | grep -v "^$" | \
read cnt1
OUTPUT TO PIPE cat WITHOUT HEADINGS
select count(*) from <tablename>;

/* In the above case the output is static that is we get only one value as the
output i amnt bothered abt the value and only the number of values obtained as output - here no of output is always = 1 */


select <col1>, <col2> from <tablename>
where <somecondition>;

/* In this case, based on the condition the output ---- > that is the no of values generated as output is varying and that in multiples of two ********
My question is how to store all the values in to variables.. preferably arrays as i have stored the output of the first query into variable cnt */

kindly help me with this issue.

gltransformfeedbackvaryings

GLTRANSFORMFEEDBACKV(3G)					    OpenGL 3.3						  GLTRANSFORMFEEDBACKV(3G)

NAME

       glTransformFeedbackVaryings - specify values to record in transform feedback buffers

C SPECIFICATION

       void glTransformFeedbackVaryings(GLuintprogram, GLsizeicount, const char **varyings, GLenumbufferMode);

PARAMETERS

       program
	   The name of the target program object.

       count
	   The number of varying variables used for transform feedback.

       varyings
	   An array of count zero-terminated strings specifying the names of the varying variables to use for transform feedback.

       bufferMode
	   Identifies the mode used to capture the varying variables when transform feedback is active.  bufferMode must be GL_INTERLEAVED_ATTRIBS
	   or GL_SEPARATE_ATTRIBS.

DESCRIPTION

       The names of the vertex or geometry shader outputs to be recorded in transform feedback mode are specified using
       glTransformFeedbackVaryings. When a geometry shader is active, transform feedback records the values of selected geometry shader output
       variables from the emitted vertices. Otherwise, the values of the selected vertex shader outputs are recorded.

       The state set by glTranformFeedbackVaryings is stored and takes effect next time glLinkProgram() is called on program. When glLinkProgram()
       is called, program is linked so that the values of the specified varying variables for the vertices of each primitive generated by the GL
       are written to a single buffer object if bufferMode is GL_INTERLEAVED_ATTRIBS or multiple buffer objects if bufferMode is
       GL_SEPARATE_ATTRIBS.

       In addition to the errors generated by glTransformFeedbackVaryings, the program program will fail to link if:

       o   The count specified by glTransformFeedbackVaryings is non-zero, but the program object has no vertex or geometry shader.

       o   Any variable name specified in the varyings array is not declared as an output in the vertex shader (or the geometry shader, if
	   active).

       o   Any two entries in the varyings array specify the same varying variable.

       o   The total number of components to capture in any varying variable in varyings is greater than the constant
	   GL_MAX_TRANSFORM_FEEDBACK_SEPARATE_COMPONENTS and the buffer mode is GL_SEPARATE_ATTRIBS.

       o   The total number of components to capture is greater than the constant GL_MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS and the buffer
	   mode is GL_INTERLEAVED_ATTRIBS.

NOTES

       glGetTransformFeedbackVarying is available only if the GL version is 3.0 or greater.

ERRORS

       GL_INVALID_VALUE is generated if program is not the name of a program object.

       GL_INVALID_VALUE is generated if bufferMode is GL_SEPARATE_ATTRIBS and count is greater than the implementation-dependent limit
       GL_MAX_TRANSFORM_FEEDBACK_SEPARATE_ATTRIBS.
