Hey all, I've three tables (g2d, dgp and pocus), with a gene-name, a score and some other information:
mysql> select * from dgp; +--------+---------------+--------------+------------------------------+------------+--------+ | chr | start | stop | gene_name | score | strand | +--------+---------------+--------------+------------------------------+------------+--------+ | chr13 | 69810099 | 70239331 | ENSG00000165659 | 738.681 | - | | chr13 | 64676788 | 65600573 | ENSG00000184226 | 627.447 | - | | chr13 | 59781822 | 59787282 | ENSG00000150506 | 619.467 | + | .... And I've a table with a lot of gene-name's. Now I want to combine these 4 tables into a fifth table, named score, wich list in the first column all the gene names, and in the three succesive columns the score for that gene from the g2d, dgp, and pocus tables, if a score is found. Otherwise the default value should be 0.00 Like this: mysql> select * from score; +------------------------------+-----------------+------------------+----------------------+ | gene_name | score_g2d | score_dgp | score_pocus | +------------------------------+-----------------+------------------+----------------------+ | ENSG00000165659 | 0.000 | 738.681 | 0.00 | | ENSG00000184226 | 123,123 | 627.447 | 0.00 | | ENSG00000999999 | 0.000 | 0.00 | 987,987 | ...... How should I construct my query? I've been trying for hours now, and can't get it rigth.
