Remove duplicates in flat file
Hi all,
I have a issues while loading a flat file to the DB. It is taking much time.
When analyzed i found out that there are duplicates entry in the flat file.
There are 2 type of Duplicate entry.
1) is entire row is duplicate. ( i can use sort | uniq) to remove the duplicated entry.
2) the PK which are forming the composite columns are same for 2 records , but the other columns are different which is also rejected and only one is getting loaded. PFB an example for the same.
My Pk are 1 , 4, 6, 8 from the flat file which is going to be loaded into the DB.
Column names : 1 2 3 4 5 6 7 8 9 10
Records 1 a b c d e f g h i j
records 2 a k l d m f n h o p
So since my PK are alone same and the rest is also different the Loader is ommiting those records. Can you tell me a script by which i can omit the record 2.
Please help.. We are in brink of issues to be fixed before tomorrow evening.
Thanks in advance
Sam

glprovokingvertex
GLPROVOKINGVERTEX(3G) [FIXME: manual] GLPROVOKINGVERTEX(3G)
NAME
glProvokingVertex - specifiy the vertex to be used as the source of data for flat shaded varyings
C SPECIFICATION
void glProvokingVertex(GLenum provokeMode);
PARAMETERS
provokeMode
Specifies the vertex to be used as the source of data for flat shaded varyings.
DESCRIPTION
Flatshading a vertex shader varying output means to assign all vetices of the primitive the same value for that output. The vertex from
which these values is derived is known as the provoking vertex and glProvokingVertex specifies which vertex is to be used as the source of
data for flat shaded varyings.
provokeMode must be either GL_FIRST_VERTEX_CONVENTION or GL_LAST_VERTEX_CONVENTION, and controls the selection of the vertex whose values
are assigned to flatshaded varying outputs. The interpretation of these values for the supported primitive types is:
If a vertex or geometry shader is active, user-defined varying outputs may be flatshaded by using the flat qualifier when declaring the
output.
NOTES
glProvokingVertex is available only if the GL version is 3.2 or greater.
ERRORS
GL_INVALID_ENUM is generated if provokeMode is not an accepted value.
