create sql query
Hi Everyone,

Can anyone pls help me out......with my requirement, i am struggling since 3 days. Please find the requirement below

my file contains below data
Code:
R1|Array/Network Resistor - VIP|V_RES_CLASS|V_MOUNT_FEATURE|SURFACE MOUNT|AND|8533.10.00.20|8533.10.00.20|
R1|Array/Network Resistor - VIP|V_RES_NW_CLASS|V_TECHNOLOGY|CARBON*||8533.10.00.20|8533.10.00.20|
R4|Array/Network Resistor - VIP|V_RES_CLASS|V_MOUNT_FEATURE|THROUGH HOLE MOUNT|AND|8533.10.00.57|8533.10.00.57|
R4|Array/Network Resistor - VIP|V_RES_NW_CLASS|V_TECHNOLOGY|CARBON*||8533.10.00.57|8533.10.00.57|
R7|Array/Network Resistor - VIP|V_RES_CLASS|V_MOUNT_FEATURE|SURFACE MOUNT|AND|8533.21.00.10|8533.21.00.25|
R7|Array/Network Resistor - VIP|V_RES_NW_CLASS|V_TECHNOLOGY|!CARBON*|AND|8533.21.00.10|8533.21.00.25|
R7|Array/Network Resistor - VIP|V_PRT_CLASS|V_MFR_PKG_DESC|DIP*||8533.21.00.10|8533.21.00.25|

i need a script to generate single sql statement for the unique column 1 attribute

if you see R7 there are 3 lines, there are 3 table names in column 3 and 3 attrributes from these tables in column 4.

my tool has to generate a sql line for R7 is
Code:
select a.V_MOUNT_FEATURE, b.V_TECHNOLOGY, c.V_MFR_PKG_DESC from V_RES_CLASS a, V_RES_NW_CLASS b, V_PRT_CLASS c where a.V_MOUNT_FEATURE='SURFACE MOUNT' and b.V_TECHNOLOGY not like 'CARBON%' and c.V_MFR_PKG_DESC like 'DIP*';

Please help me out.

Thanks,
Jam

Try and adapt the following AWK script :
Code:
nawk -F'|' -v Q="'" '
{
    req       = $1;
    table     = $3;
    column    = $4;
    attribute = $5;
    nbTbl     = ++Requests[req];     # Tables count
    Tables[req, nbTbl]     = table;
    Columns[req, nbTbl]    = column;
    Attributes[req, nbTbl] = attribute;
}
END {
    tblIds = "abcdefghijklmnopqrstuvwxyz";
    for (req in Requests) {
        nbTbl  = Requests[req]
        select = "";
        where  = "";
        from   = "";
        sep    = "";
        for (i=1; i<=nbTbl; i++) {
            id        = substr(tblIds,i,1);
            select    = select sep id "." Columns[req, i];
            from      = from   sep Tables[req, i] " " id;     
            attribute = Attributes[req, i];
            if (attribute ~ /[*%]/) {
                not = "";
                if (substr(attribute,1,1) == "!") {
                    not = "NOT ";
                    attribute = substr(attribute,2);

Hi aigles,

Thanks for your help!!!!!! I will call your awk scipt in my perl script. I need some modification with reference to below file
Code:
R1|Array/Network Resistor - VIP|V_RES_CLASS|V_MOUNT_FEATURE|SURFACE MOUNT|AND|8533.10.00.20|8533.10.00.20|
R1|Array/Network Resistor - VIP|V_RES_NW_CLASS|V_TECHNOLOGY|CARBON*||8533.10.00.20|8533.10.00.20|
R4|Array/Network Resistor - VIP|V_RES_CLASS|V_MOUNT_FEATURE|THROUGH HOLE MOUNT|AND|8533.10.00.57|8533.10.00.57|
R4|Array/Network Resistor - VIP|V_RES_NW_CLASS|V_TECHNOLOGY|CARBON*||8533.10.00.57|8533.10.00.57|
R7|Array/Network Resistor - VIP|V_RES_CLASS|V_MOUNT_FEATURE|SURFACE MOUNT|AND|8533.21.00.10|8533.21.00.25|
R7|Array/Network Resistor - VIP|V_RES_NW_CLASS|V_TECHNOLOGY|!CARBON*|AND|8533.21.00.10|8533.21.00.25|
R7|Array/Network Resistor - VIP|V_PRT_CLASS|V_MFR_PKG_DESC|DIP*||8533.21.00.10|8533.21.00.25|

in the created sql query i need to add two static table v_prt_class and v_vmf_class in all the query as i need to extract one attribute from each of these two tables,
condition here is if v_prt_class part of the it should not duplicate

If u take the first output it does not contain V_PRT_CLASS table in the query, if u take 3rd output it contains V_PRT_CLASS table.

new sqlquery for the 3rd output should be
Code:
select a.v_prt_nbr, b.v_vmf_name, c.V_MOUNT_FEATURE, d.V_TECHNOLOGY, a.V_MFR_PKG_DESC from v_prt_class a, v_vmf_class b, V_RES_CLASS c, V_RES_NW_CLASS d where c.V_MOUNT_FEATURE='SURFACE MOUNT' and d.V_TECHNOLOGY NOT LIKE 'CARBON%' and a.V_MFR_PKG_DESC LIKE 'DIP%' and a.obj_id=c.obj_id and c.obj_id=d.obj_id and a.V_PRT_MFG_PTR=b.obj_id;

here a.obj_id=c.obj_id and c.obj_id=d.obj_id and a.V_PRT_MFG_PTR=b.obj_id; is a static line
for 1st output
Code:
select a.v_prt_nbr, b.v_vmf_name, c.V_MOUNT_FEATURE, d.V_TECHNOLOGY from v_prt_class a, v_vmf_class b, V_RES_CLASS c, V_RES_NW_CLASS d where c.V_MOUNT_FEATURE='SURFACE MOUNT' and d.V_TECHNOLOGY LIKE 'CARBON%' and a.obj_id=c.obj_id and c.obj_id=d.obj_id and a.V_PRT_MFG_PTR=b.obj_id;

Instead of writing the output to terminal I need to write it to some output file, Also I need to retain clolumn 1 ,7 and 8 along with the corresponding query.
